Opis:
Objectives: The brick field industry is one of the oldest industries in India, which employs a large number of workers of poor socioeconomic status. The main aim of the present investigation is i) to determine the prevalence of musculoskeletal disorders among brick field workers, ii) to determine the prevalence of respiratory disorders and physiological stress among brick field workers compared to control workers. Material and Methods: For this study, a total of 220 brick field workers and 130 control subjects were selected randomly. The control subjects were mainly involved in hand-intensive jobs. The Modified Nordic Questionnaire was applied to assess the discomfort felt among both groups of workers. Thermal stress was also assessed by measuring the WBGT index. The pulmonary functions were checked using the spirometry. Physiological assessment of the workload was carried out by recording the heart rate and blood pressure of the workers prior to work and just after work in the field. Results: Brick field workers suffered from pain especially in the lower back (98%), hands (93%), knees (86%), wrists (85%), shoulders (76%) and neck (65%). Among the brick-making activities, brick field workers felt discomfort during spading for mud collection (98%), carrying bricks (95%) and molding (87%). The results showed a significantly lower p value < 0.001 in FVC, FEV₁, FEV₁/FVC ratio and PEFR in brick field workers compared to the control group. The post-activity heart rate of the brick field workers was 148.6 beats/min, whereas the systolic and diastolic blood pressure results were 152.8 and 78.5 mm/Hg, respectively. Conclusions: This study concludes that health of the brick field workers was highly affected due to working in unhealthy working conditions for a long period of time.

Opis:
Sixty female prawn seed collectors and 60 female control subjects from Sajenakhali and Sandeshkhali blocks of Sunderbans, West Bengal, India, were randomly selected to evaluate and compare musculoskeletal disorders and physiological stress. The control group was engaged in domestic work involving minimum handintensive activities. The modified Nordic musculoskeletal questionnaire and rapid entire body assessmentwere used. Most subjects suffered from discomfort in different body parts, especially in the lower back (98%), knees (88%), shoulders (75%), ankles (70%) and feet (67%). This study reveals that female prawn seed collectors suffer from significant physiological load and extreme physiological stress due to prolonged working hours in a standing posture and excessive work pressure. Consequently, all these factors affect female prawn seed collectors’ health and work performance.

Opis:
A pot experiment was conducted to examine whether the morphological and physiological characteristics of some halophytes may be affected by salt stress. For this purpose, a factorial experiment based on randomized complete block design was carried out with three replications. The treatments were some halophytes (Salicornia europaea, Atriplex leucoclada, and Kochia scoparia) and salinity stress levels [Electrical conductivity 0 (Hoagland’s solution), Hoagland’s solution consisting of 100, 200, 300 and 500 mM NaCl]. Among the halophytes tested, Salicornia europaea had significantly higher shoot and root of dry matters compared to the other halophytes in all salt treatments. Salinity stress resulted in an increase in photosynthetic pigments up to 200 mM and thereafter, it decreased in all of the studied plants. Photosynthetic pigments, ranked in a descending order, were high in Kochia scoparia, Salicornia europaea, and Atriplex leucoclada. In addition, salinity stress led to an enhancement in malondialdehyde (MDA) and H2O2. The tolerance of Salicornia europaea under high salinity stress was associated with low MDA and H2O2 contents as well as high contents of photosynthetic pigments. The shoot and root Na+ increased considerably by augmenting the salinity levels in all halophytic plants; however, there was a significant difference among halophytes at higher salinity levels. The shoot K+ decreased by increasing the salinity levels, but K+ partitioning pattern varied among the halophytes. Under saline conditions, the shoot and root Na+/K+ ratio of all halophytes grew. The highest and the lowest of Na+ were observed in Salicornia europaea and Kochia scoparia, respectively. Thus, the Na+/K+ ratio could be considered as an indicator of salt evaluation. Nitrogen, protein content, dry matter digestibility (DMD), and metabolizable energy (ME) were high in Salicornia europaea plants in comparison to other plants at 200–500 mM salinity levels; in contrast, acid detergent fiber (ADF) and netural detergent fiber (NDF) were low. According to the results of this study, the tolerance of halophytes towards NaCl is possibly due to the differences in damage from reactive oxygen species (ROS), especially H2O2, and toxicity to metabolism Na+.

Opis:
Emergency work can expose personnel to sleep restriction. Inadequate amounts of sleep can negatively affect physiological and psychological stress responses. This review critiqued the emergency service literature (e.g., firefighting, police/law enforcement, defense forces, ambulance/paramedic personnel) that has investigated the effect of sleep restriction on hormonal, inflammatory and psychological responses. Furthermore, it investigated if a psycho-physiological approach can help contextualize the significance of such responses to assist emergency service agencies monitor the health of their personnel. The available literature suggests that sleep restriction across multiple work days can disrupt cytokine and cortisol levels, deteriorate mood and elicit simultaneous physiological and psychological responses. However, research concerning the interaction between such responses is limited and inconclusive. Therefore, it is unknown if a psycho-physiological relationship exists and as a result, it is currently not feasible for agencies to monitor sleep restriction related stress based on psycho- physiological interactions. Sleep restriction does however, appear to be a major stressor contributing to physiological and psychological responses and thus, warrants further investigation.

Opis:
e adaptability of plants to drought not only includes their ability to resist drought stress, but also their ability to recover aer stress is relieved. In this study, a weighting method was used to control the soil water content to produce a soil water stress gradient. e effects of drought and rewatering on the changes in osmotic adjustment substance content, antioxidant enzyme activity, and photosynthetic characteristics of potted Dicranostigma henanensis seedlings were measured on Day 28 aer the imposition of watering treatments and Day 7 aer rewatering. During the drought stress process, the relative electrical conductivity, thiobarbituric acid, water use efficiency, and proline content displayed a continuously increasing trend. Further, the net photosynthetic rate, stomatal conductance, and transpiration rate constantly decreased, while the chlorophyll content first increased and then decreased. Aer rehydration, superoxide dismutase (EC 1.15.1.1) activity and photosynthetic parameters quickly recovered to the CK level (soil moisture is 75%–80% of the maximum water holding capacity in the field), indicating that D. henanensis plants have a strong ability to repair the damage caused by drought stress. In particular, the photosynthetic machinery may have sophisticated regulation and repair mechanisms, which may be associated with its stable photosystem. Collectively, our findings demonstrate that the D. henanensis plant has a strong ability to adapt to arid environments, and therefore could be an excellent ornamental flower for landscaping in arid and semiarid areas.

Opis:
Stress is an integral part of our lives. It also applies to our childhood. That is why it is so important to know how children cope with stress (how they learn coping strategies) and to equip them with the skill set to cope constructively with stressful situations throughout life. This article describes strategies for coping with stress that are characteristic for children at the end of early school education. They have been identified in the course of my own research aimed at characterizing child stress and relate to a fragment of research activities aimed at 8- and 9-year-old children. The research established that in some children the developmental process of coping with stress has started: children look for, investigate, and think how to cope with difficulties. In this struggle, however, they focus on people ho could be a source of support for them in coping with stressful situations. Among children’s stress coping strategies, an important role is also played by emotionally focused strategies, which are aimed at reducing negative emotions and arousing positive emotions.

Opis:
Braya humilis (Brassicaceae) is a widely distributed plant in arid and semi-arid regions of northern Asia. This plant is well adapted to extremely arid conditions and is a promising candidate species to discover novel drought tolerance strategies. However, not much information about the mechanism(s) mediating drought resistance in this species is currently available. Therefore, the present study aimed to characterize the physiological traits and expression patterns of a polyethylene glycol (PEG)-responsive gene in B. humilis responding to different levels of osmotic stress induced by PEG-6000. Several important physiological parameters were examined, including the levels of relative water content, soluble protein, malondialdehyde, and antioxidant enzyme activity. A tolerance threshold between 20 and 30% PEG-6000 was identified for B. humilis. The water status and oxidative damage below this threshold were maintained at a relatively constant level during the 12 h of treatment. However, once the threshold was exceeded, the water status and oxidative damage were obviously affected after treatment for 4 h. The soluble protein results suggest that B. humilis maintains a vigorous resistance to osmotic stress and that it may play a greater role in osmotic regulation at late stages of stress. Moreover, superoxide dismutase and catalase may be important at preventing oxidative damage in plants at early stages of stress, while peroxidase may be more involved in some biological processes that resist osmotic stress at the late stage, especially in severely damaged plants. Furthermore, a PEG-responsive gene, BhCIPK12, was identified by differential display reverse transcription-polymerase chain reaction (PCR), cloned, and characterized by quantitative real-time PCR. We hypothesized that this gene may play an important role in mediating osmotic stress or drought resistance in plants. Altogether, these results provide valuable insights into the mechanism(s) mediating drought tolerance in B. humilis.

Opis:
A relationship between jasmonates and ethylene in regulation of some physiological processes in plants under stress conditions is presented. Jasmonates are naturally occurring plant hormones showing various important biological activities in the regulation of plant growth development and in defense responses against a wide variety of abiotic and biotic agents. Jasmonates have been reported to control ethylene biosynthesis in intact plants and their organs. Mechanical wounding and other abiotic (osmotic stress, water deficit, dessication stress, heavy metals, touch, ozone) and biotic stresses (pathogen infection and insect invasion) are well known to be common factors inducing ethylene and jasmonates biosynthesis, and reactive oxygen species generation (ROS). Jasmonates have been well known to interact with ethylene in regulation of different processes; various kinds of interactions were documented: 1) synergistic interaction (i.e gene expression of proteinase inhibitors, osmotin, defensin), 2) ethylene suppresses processes induced by jasmonates (i.e. biosynthesis of nicotine, vegetative storage proteins and lectins), 3) jasmonates suppress processes induced by ethylene (i.e. ethylene-induced apical hook). Jasmonic acid carboxyl methyltransfe- rase (JMT) is a key enzyme for jasmonate-regulated plant responses. Activation of JMT expression leads to production of methyl jasmonate (JA-Me). JA-Me can act as an intracellular regulator, a diffusible intercellular signal transducer, or an airborne signal mediating intra- and interplant communications. Jasmonates represent an integral part of the signal transduction chain between stress signals) and stress responses(s), in most cases of the induction of gene expression and the accumulation of defense specific proteins and secondary metabolites.
Zależności między jasmonianami i etylenem w regulacji niektórych procesów fizjologicznych u roślin w warunkach stresowych są przedmiotem tego przeglądu. Jasmoniany są naturalną grupą hormonów roślinnych i wykazują wiele ważnych funkcji fizjologicznych w regulacji wzrostu i rozwoju roślin i w reakcjach obronnych przeciwko różnym czynnikom abiotycznym i biotycznym. Wykazano, że jasmoniany odgrywają ważną rolę w regulacji biosyntezy etylenu w roślinach nienaruszonych i ich organach. Mechaniczne uszkodzenie i inne czynniki abiotyczne (stres osmotyczny, deficyt wodny, stres desykacyjny, metale ciężkie, dotyk, ozon) i czynniki biotyczne (infekcja przez patogeny i żerowanie owadów) powodują wzmożoną biosyntezę etylenu i jasmonianów oraz generowanie reaktywnych form tlenu (ROS). Jasmoniany współdziałają z etylenem w regulacji różnych procesów, a interakcje te mają różny charakter: 1) synergistyczne współdziałanie (np. ekspresja genów inhibitorów proteinaz, osmotyny, defenzyny), 2) etylen hamuje procesy indukowane przez jasmoniany (np. biosynteza nikotyny, wegetatywnych białek zapasowych, lektyn), 3) jasmoniany hamują procesy indukowane przez etylen (np. wygięcia części wierzchołkowych powodowane przez etylen). Metylotransferaza karboksylową kwasu jasmonowego (JMT) jest kluczowym enzymem w procesach regulowanych przez jasmoniany w roślinach. Aktywacja ekspresji JMT doprowadza do powstawania jasmonianu metylu (JA-Me) z kwasu jasmonowego. JA-Me może działać jako regulator w obrębie komórki i jako międzykomórkowy sygnał transdukcyjny, a jako lotna substancja stanowi przekaźnik informacji między roślinami. Sugeruje się, że endogenne jasmoniany stanowią przekaźnik informacji między sygnałem stresowym a reakcją stresową, polegającą głównie na indukcji ekspresji genowej i biosyntezie specyficznych białek i metabolitów wtórnych.

Opis:
Stres jest jedną z głównych przyczyn problemów ze zdrowiem psychofizycznym i prowadzi do spadku efektywności pracy. Odpowiednie metody diagnozowania poziomu stresu pozwalają na rzetelną weryfikację efektywności interwencji mających na celu jego redukcję, a także ocenę różnic indywidualnych w reaktywności na stres. Celem pracy było przeprowadzenie przeglądu dostępnych badań, w których wykorzystano najczęściej stosowane protokoły wzbudzania stresu w warunkach laboratoryjnych i dokonano pomiarów stresu za pomocą parametrów fizjologicznych. Do przeglądu włączono badania wykorzystujące protokoły: MIST, MA, TSST, test Stroopa i PASAT, oraz uwzględniające pomiar aktywności mózgu i serca, stężenia kortyzolu oraz napięcia mięśniowego. Do analiz włączono prace dostępne w bazie PubMed i opublikowane w latach 2015–2021, w których badania przeprowadzono z udziałem zdrowych osób dorosłych. Analiza dostępnych badań ujawniła, że procedury wywołują zmiany aktywności autonomicznego układu nerwowego, układu sercowo-naczyniowego i mózgu. Ponadto TSST jest protokołem wykorzystywanym najczęściej do oceny poziomu stresu, różnic reaktywności na wzbudzony stres w zależności od różnic między osobami w poziomie natężenia cech osobowości bądź porównania konkretnych grup osób. W pomiarach wzbudzonego stresu zazwyczaj wykorzystuje się analizę stężenia kortyzolu w odpowiedzi na stres i zmiany w aktywności serca. Powszechnie stosowaną metodą w badaniach neuroobrazowych jest zadanie MIST. Analiza wyników badań ujawniła, że protokoły, oprócz wzbudzania typowej reakcji fizjologicznej, w przypadku niektórych osób łączą się z osłabieniem reakcji fizjologicznych na stres.
Stress is one of the main reasons for deterioration in mental and physical health, and it leads to a decrease in work efficiency. Providing appropriate methods of diagnosing the level of stress allows for making a reliable verification of the effectiveness of stress reduction interventions and for assessing individual differences in reactivity to stress. The aim of this study was to review the available studies that use the most common stress induction protocols in laboratory settings and measure psychophysiological reactions to stress. The review included research using the following protocols: MIST, MA, TSST, Stroop Test and PASAT, and measuring brain activity, heart activity, cortisol levels and muscle tones. The analyzes included papers available in the PubMed database, published in 2015‒2021, in which studies were conducted on healthy adults. The analysis of the available studies revealed that the protocols induced changes in the activity of the autonomic nervous system, the cardiovascular system and brain activity. Moreover, TSST is a protocol that is most often used to assess the level of stress and differences in reactivity to induced stress depending on individual differences in personality traits, and to make the comparison of specific groups of people. Measurements of induced stress are usually done by analyzing the cortisol levels in response to stress and changes in heart activity. The MIST test is a commonly used method in neuroimaging studies. The analysis of the research results has revealed that the protocols, beside inducing a typical physiological response, are associated with blunting the physiological response to stress in some people.

Opis:
This study was aimed at evaluating the effect of sublethal doses of glyphosate on physiological parameters of a common ornamental plant Mexican marigold (Tagetes erecta). The herbicide was applied in the following doses: 720 g ⋅ ha–1 (standard field dose), 144 g ⋅ ha–1, 28.8 g ⋅ ha–1, and 14.4 g ⋅ ha–1, in the form of a spraying treatment of plants in a specialist spraying chamber. The net assimilation rate and leaf greenness index were then determined. Herbicide application in the sublethal doses, i.e. below 720 g ⋅ ha–1, caused disorders in both analyzed physiological parameters of plants. The glyphosate dose of 144 g ⋅ ha–1 elicited transient disorders in the leaf greenness index. In turn, the use of the lower doses (28.8 g ⋅ ha–1 and 14.4 g ⋅ ha–1) caused a short-term increase in the net photosynthesis rate in the plants which was accompanied by a decreased value of the leaf greenness index. Study results demonstrated the effect of sublethal doses of glyphosate as a stress factor in parameters associated with the process of photosynthesis in plants.

Opis:
Objectives The objectives of these investigations completed on workplaces in the Hungarian mining industry were to characterize the physiological strain of workers by means of work pulse and to examine the effects of work-related psychological factors. Material and Methods Continuous heart rate (HR) recording was completed on 71 miners over a total of 794 shifts between 1987 and 1992 in mining plants of the Hungarian mining industry using a 6-channel recorder – Bioport (ZAK, Germany). The work processes were simultaneously documented by video recording along with drawing up the traditional ergonomic workday schedule. All workers passed health evaluation for fitness for work. The effects of different psychological factors (simulated danger, “instrument stress,” presence of managers, and effect of prior involvement in accidents as well as different mining technologies and work place illumination) on the work pulse were evaluated. The statistical analysis was completed using SPSS software (version 13.0, SPSS Inc., USA). Results The work-related physiological strain differed between work places with different mining technologies in groups of 12–18 workers. The work pulse was lowest in bauxite mining (ΔHR = 22±8.9 bpm) and highest in drift drilling in dead rock with electric drilling machine (ΔHR = 30±6.9 bpm). During sham alarm situation the work pulse was significantly higher than during normal activities with the same physical task (ΔHR = 36.7±4.8 bpm vs. 25.8±1.6 bpm, p < 0.001). When work was performed under different psychological stress, the work pulse was consistently higher, while improving the work place illumination decreased the physiological strain appreciably (ΔHR (median, 25–75 percentiles) = 23, 20–26 bmp vs. 28, 25–31.3 bpm, p < 0.001). Conclusions Recording the heart rate during whole-shift work along with the work conditions gives reliable results and helps isolating factors that contribute to increased strain. The results can be used to implement preventive and health promotion measures.

Opis:
The physiological response of Phalaenopsis × hybridum ‘Innocence’ to biotic stress caused by Pseudococcus longispinus feeding was investigated. The condition of the cytoplasmic membranes expressed by a value of electrolyte outflow (EL) and TBARS and the activity of antioxidative system enzymes: catalase and peroxidase, and the amount of non-enzymatic antioxidant – proline, were determined. The changes in all the analyzed physiological parameters depended on the duration of the pest feeding. The outflow of electrolytes, TBARS content and catalase activity was the highest in the first period of the experiment (after 24-hour of mealybug feeding). Significant increase of peroxidase activity and proline content was noted after 7 days of insects feeding. The values of all analyzed parameters (except EL) demonstrated a decreasing tendency after 14 days of P. longispinus feeding. The observed reaction of P. hybridum ‘Innocence’ testifies to mechanisms triggered with the aim of neutralizing the effects of biotic stress and enabling the normal functioning of the cells in the orchid plants colonized by longtailed mealybug.
Badano fizjologiczną reakcję P. × hybridum ‘Innocence’ na stres biotyczny wywołany żerowaniem P. longispinus. Określono stan błon cytoplazmatycznych wyrażony wartością wypływu elektrolitów (EL) i zawartością substancji reagujących z kwasem tiobarbiturowym (TBARS), a także aktywność enzymów systemu antyoksydacyjnego: katalazy i peroksydazy, oraz ilość nieenzymatycznego antyoksydanta – proliny. Zmiany w wartowniach wszystkich analizowanych parametrów zależały od długości żerowania szkodnika. Wartość EL, zawartość TBARS oraz aktywność katalazy były najwyższe w pierwszym terminie eksperymentu (24-godzinne żerowanie czerwca). W przypadku aktywności peroksydazy i zawartości proliny istotny wzrost notowano dopiero po 7 dniach Żerowania. Po 14 dniach od zasiedlenia storczyków wartości wszystkich analizowanych parametrów (wyjątek EL) wykazywały wyraźną tendencję spadkową. Obserwowana reakcja P. hybridum ‘Innocence’ świadczy o uruchomieniu przez rośliną mechanizmów, których zadaniem jest neutralizacja skutków stresu biotycznego i umożliwienie komórkom powrotu do normalnego funkcjonowania.

Opis:
Seed priming is one of the potential physiological approaches to enhance the seed germination under the salinity stress. The present study examined the role of two seed priming molecules: salicylic acid (SA) and hydrogen peroxide (H2O2), in enhancing the salt tolerance of lentil seeds at germination stage. Salinity stress caused significant decrease in germination percentage and primary root elongation. This decrease was associated with significant increase in lipid peroxidation and total lipid (TL) contents in embryonic axis. The catalase (CAT), guaiacol peroxydase (GPOX) and superoxide dismutase (SOD) activities remained unchanged or decreased significantly under the influence of salt stress, in both embryonic axis and cotyledons. Starch mobilization was not affected by the salt stress. The two priming treatments effectively alleviated the negative effects of salinity stress. SA and H2O2 applications after dose optimization resulted in a significant enhancement of germination percentage and primary root elongation. No significant changes in starch, soluble sugars contents and SOD activity were detected following SA and H2O2 treatments. Seed priming treatments triggered the activities of GPOX and CAT and caused the reduction in lipid peroxidation, especially in embryonic axis. TL content and especially the fatty acid C18:3 increased after SA applications. Better performance under salt stress of primed lentil seeds was associated with lower lipid peroxidation, and activation of enzymatic antioxidative defense system. Obtained results confirm the potential for using SA and H2O2 to improve germination and plant growth under salt stress conditions.

Opis:
This research was conducted to evaluate the effects of water salinity and nano-silica (NS) and humic acid (HA) on Bermuda grass. The study was carried out under greenhouse and exterior space conditions in a completely randomized design with factorial arrangements. Treatments included 4 water salinity levels (0, 5, 7 and 9 dS/m) and 4 level of NS (0, 1, 2 and 3 mm/l) as well as 4 level of HA (0, 50, 100 and 150 mg/l). Results indicated a decrease in chlorophyll content, and increase in proline, malondialdehyde (MDA), catalase (CAT), superoxide dismutase (SOD) and electrolyte leakage (EL) with increasing levels of salinity. The chlorophyll content in greenhouse and exterior space also increased with increasing levels of NS and HA, while proline in two environments, with increasing levels of NS and HA decreased. EL with increasing levels of NS fluctuated, but with increasing levels of HA, it decreased in two environments. With increasing levels of NS, CAT in both environments was eventually decreased after the oscillation, but there was no particular trend in HA levels. With increasing levels of NS and HA, MDA in the greenhouse decreased and in the exterior space – it increased. Finally, by increasing levels of NS and HA, SOD did not show any change in the greenhouse condition, but in the exterior space, the SOD was decreased.

Opis:
This study consists of assessments of the thermal environment and physiological strain in tasks associated with airport, construction, and metal jobs. The number of male and female participants was 108. Environmental heat stress was evaluated with the WBGT index. Physiological strain was evaluated by the relative cardiovascular load (%CVL) based on the measurements of heart rate. Also the increase of body temperature, weight loss, and perceived discomfort were determinated. At work sites the assessments lasted for 2 to 4 hrs for each participant. The mean physiological strain exceeded the level of 30%CVL. Severe peaks (over 60%CVL) were observed in specific tasks being in agreement with perceived discomfort ratings. The increase of body temperature and weight loss in most cases remained within acceptable limits. For the most strenuous tasks, various ergonomic improvements were developed in consultation with workers and managers.

Opis:
Five students of a rescue training school cycled at 50 W for 20 min at 20 oC before walking at 5 km/hr up to 30 min in a climatic chamber at 55 oC and 30% relative humidity. 4 different types of clothing ensembles differing in terms of thickness and thermal insulation value were tested on separate days. All subjects completed 28–30 min in light clothing, but quit after 20–27 min in 3 firefighter ensembles due to a rectal temperature of 39 oC or subjective fatigue. No difference in the evolution of mean skin or rectal temperature was seen for the 3 turnout ensembles. Sweat production amounted to about 1000 g in the turnout gears of which less than 20% evaporated. It was concluded that the small differences between the turnout gears in terms of design, thickness and insulation value had no effect on the resulting heat physiological strain for the given experimental conditions.
