Outcomes of distal femoral fractures helped by energetic condylar screw (DCS) plate technique: just one centre encounter occupying Many years.
Macrophages are considered to be key players in innate immunity and inflammatory responses. Domestic cattle with standard body size quickly reach their heat tolerance limit and are prone to heat stress. The combined effects of high temperature and endotoxemia on bovine monocyte-derived macrophages remain almost undisclosed. This study aims to unravel the molecular and functional responses of bovine monocyte-derived macrophages to thermal cum lipopolysaccharide induced stress challenge in vitro. The cells were incubated at 37 °C or 40 °C with lipopolysaccharide (1.0 μg/mL) for 24 h and 48 h. At the end of each treatment, cell viability, apoptotic rate, mitochondrial membrane potential, oxidative activity, phagocytosis, and autophagy functions were assessed and mRNA abundance of genes related to heat shock (HSP 70), inflammation (IL1β, IL6, IL 12, TNF, INF γ), cell signalling (TLR4), cell viability (Bax, Bcl2), nitric oxide synthesis (NOS2) and natural resistant associated macrophage protein were quantified by quantitative polymerase chain reaction (qPCR). The results revealed the increased apoptosis, reduced mitochondrial membrane potential, and cell viability, decreased oxidative and phagocytosis ability in cells co-stimulated with LPS and thermal stimuli. Upregulation of HSP 70 gene and downregulation of natural resistant associated macrophage protein, cell signalling, and inflammation related genes mRNA expressions were also identified due to these stressors. In conclusion, the observed thermal cum LPS stress induced dysregulation in macrophage functionality may be one facet of the increased disease susceptibility in dairy cattle during thermal stress.The present study to evaluated the effect of different thermal regimes on growth performance, oxidative stress, antioxidant enzymes, and immuno-biochemical responses of endangered golden mahseer, Tor putitora. A total of 144 healthy fingerlings were randomly distributed into four experimental groups (13 °C, 16 °C, 19 °C, 22 ± 0.5 °C) in triplicate rectangular fiberglass reinforced plastics tanks. The highest and lowest Growth rate, Specific growth rate, Daily growth index, Thermal growth coefficient, Viscera-somatic index, and Growth hormone were observed at 19 °C and 13 °C, respectively. The lowest SGR and VSI were observed at 22 °C. The feed conversion ratio was significantly higher in the control group (p 0.05) impact of temperature regimes were observed on the length-weight relationship. Regarding hematological indices results, the hematocrit, hemoglobin, total erythrocyte count, and total leucocyte count were significantly higher at 13 °C, whereas the lowest was observed in all the treatment groups (p less then 0.05). Higher myeloperoxidase activity and lysozyme activity were observed at 13 °C, whereas lowest at 22 °C. Anti-oxidant potential, SOD, and catalase (muscle) were significantly higher in the control group, whereas they gradually decreased with an increasing temperature. Catalase (liver) level was significantly higher at 22 °C. GST content was significantly higher at 22 °C compared to 13 °C, and GST content increased gradually with an increased temperature. The lipid peroxidation level in the liver and muscle was significantly higher at 22 °C and 13 °C, respectively. The present study concluded that the different phenotypic, antioxidative, and immuno-biochemical modulations of golden mahseer fingerlings in response to different temperature regimes could be used for better management and propagation.The study was aimed at evaluating the concentration of serum thyroid hormones and diurnal trends in rectal and body surface temperatures in neonatal buck-kids and doelings. Rectal and body surface (eye, head and trunk) temperatures as well as the differences between rectal and surface (DBRS) temperatures were determined in 39 kids, having equal number of Red Sokoto, Sahel and West African Dwarf (WAD) goats during daytime nadir (0700 h) and zenith (1300 h) in ambient temperatures. All variables and blood samples were obtained from birth to Day 20, post-natal. Results revealed significantly (P less then 0.05) lower values of morning and afternoon rectal temperatures at birth with subsequent post-natal increase, attaining higher stable values after Day 2. Morning head surface temperature decreased significantly after birth, whereas, DBRS temperatures were lower at birth and increased in subsequent days. From birth, diurnality was distinct (P less then 0.05) in all body surface and DBRS temperatures, while, d respectively.Females and males have divergent strategies of energy investment, so the thermal preference of each sex in insects may differ because energetic conversion of metabolic reserves is dependent on temperature. We determined the thermal preference of virgin, sexually mature Mediterranean fruit flies, Ceratitis capitata, and found that males preferred a significantly higher temperature (23.8 ± 0.3 °C) than that of females (22.1 ± 0.3 °C). We then tested predictions for the difference in thermal preference related to the energetic demands of reproduction over a range of temperatures. The frequency and duration of calling bouts by male C. capitata were optimal at 26 °C. Mating propensity and latency, and copula duration, were optimal over the range of 22-28 °C. When mating occurred, temperature had little effect on the incidence of sperm storage by females, but there was a notable decline in the number stored at 28 °C. Female lifespan was highest at 18 °C, but lifetime egg production was optimal at 24 °C. These results illustrate temperature-related differences in the reproductive fitness of the sexes in C. capitata, although the optima for male traits align best with their thermal preference. They also support the theoretical prediction that insect thermal preference should be lower than the optimum for fitness.The ambient temperature of the environment influences the life history features of the land snails, thereby affecting the life history strategies. With the temperature being a reliable indicator of the seasonal changes, an attempt to explore the variations in the life history strategies of the pest snail Allopeas gracile (Hutton, 1834) (Gastropoda Subulinidae) was carried out under four constant temperature grades - 15°C, 20°C, 30°C and 35°C (±1°C) temperatures throughout with laboratory temperature as controlled environment. The snail A. gracile was unable to complete their life cycle at 15°C and 20°C, without reaching reproductive maturity. In contrast, A. gracile maintained at laboratory temperatures (range 25-29 °C) exhibited long life span, longer reproductive period and longer generation time. However, the reproductive rate was highest at temperature 30°C. Perhaps, the warmer environment facilitated rapid growth, fast onset of reproduction with larger body size at early age. At a constant higher temperature of 35°C a state of inactivation was imposed when growth and reproduction became static. Apparently, the expression of the life history traits of A. SCH-527123 supplier gracile was supportive of an invasive nature, at a temperature ranging between 25°C and 35°C.Climate change is expected to increase mean temperatures and the frequency of extreme weather events, that can lead to earlier/extended breeding seasons in temperate taxa. As a consequence, many organisms that show climate-induced phenological shifts might be exposed to environmental conditions they are not well adapted to while breeding, and their ability to cope with stressful conditions might be influenced. Here, we investigated how parental breeding time shapes the sensitivity to nitrate exposure at three consecutive life stages (embryonic, larval, juvenile) in the European common frog (Rana temporaria). We compared hatching success and life-stage specific survival, growth, standard metabolic rate, body condition, and acute thermal sensitivity of offspring from an earlier-breeding parental cohort (early cohort) vs. a later-breeding parental cohort (late cohort) exposed to a range of environmentally relevant concentrations of nitrate (0-100 mg/L). We also investigated whether nitrate exposure experienced dtheir consequences on species subjected to them.Winter-active arthropod predators (like vegetation-dwelling spiders) significantly suppress pest populations during winter in pome fruit orchards in Central Europe. Clubiona spiders are very abundant in orchards and have been observed to be active during winter. Here, we performed laboratory experiments to assess the movement and predation activity of clubionids at low temperatures. In addition, we also assessed prey survival (psyllids and crickets). We revealed that Clubiona spiders actively moved even at a temperature below 0 °C. Pest prey (Cacopsylla sp.) was able to survive at low temperatures, but crickets died at 3 and -1 °C. Overall Clubiona activity was very low but present during the whole observation period of five days. The predation activity of Clubiona declined with lower temperatures for both cricket and pest (Cacopsylla sp.) prey. Nevertheless, 44% and 25% of Clubiona individuals captured and consumed psyllid and cricket prey, respectively, even at the lowest temperature of -1 °C. Our results show that Clubiona spiders are active predators at low temperatures and, therefore, should contribute to the suppression of overwintering pest populations.This study aimed to evaluate the reliability of a patch-type sensor on the upper chest region that uses a dual-heat-flux method to estimate core temperature under various heat conditions. The participants' esophageal and rectal temperatures (Teso and Trec) were measured with real-time monitoring of predicted core temperature (Tpre) using the patch. Twenty-one volunteers wearing work clothes and nine volunteers wearing protective clothing walked (5.0 km/h) for an hour at 35 °C. During exercise, Teso increased to 37.9 ± 0.3 °C and 38.2 ± 0.2 °C for each group, respectively. The root mean squared errors (RMSEs) were 0.18 ± 0.05 °C and 0.25 ± 0.08 °C between Teso and Tpre and were 0.31 ± 0.10 °C and 0.34 ± 0.11 °C between Trec and Tpre in each clothing condition, respectively. In addition, 11 volunteers walked for an hour at 30 °C or 40 °C. The Teso during exercise increased to 37.7 ± 0.3 °C and 38.2 ± 0.3 °C, respectively. The RMSEs were 0.23 ± 0.10 °C and 0.18 ± 0.05 °C between Teso and Tpre in each ambient temperature condition, respectively. Furthermore, eight volunteers performed an arm-cranking exercise (60 W) for 30 min at 35 °C. The Teso increased to 37.9 ± 0.2 °C during exercise. The RMSEs were 0.22 ± 0.07 °C between Teso and Tpre. The proportions of all paired measurements differing by less than the predefined threshold for validity of ≤ 0.3 °C were 85 ± 18% between Teso and Tpre. These data indicate that the patch is capable of providing a moderate estimate of core temperature during low-intensity and acute exercise under heat conditions.The understanding of heat conduction during finger contact with cooler or hotter objects is important for designing many electronic devices and for setting safety standards in a variety of occupational settings. In the most common experimental approach to study this process, a micro-thermocouple is placed at the finger-object interface. However, the interpretation of what this measurement corresponds to is not clear. To this end, we develop a three-dimensional thermal simulation of the finger-thermocouple-substrate configuration. The model predictions match finger cooling measurements in eight distinct cases available in prior literature (finger pressed with 1 N or 9.8 N against a steel or an aluminum substrate held at -2 °C or -10 °C). We demonstrate that the thermocouple can be represented accurately as a truncated sphere with emerging cylindrical wires while a multilayer block model of the finger provides similar results to an anatomically representative model. Our simulations show that in the eight previously studied cooling cases, the average surface temperature of skin that is in contact with the substrate follows nearly the same but offset cooling trend as the thermocouple tip temperature.
