Intense training regimes are practiced across military facilities to develop soldiers’ mental and physical abilities to meet the demands of modern-day warfare. Two short-duration military runs through the jungle and flat natural tracks were selected to quantify their mental and physiological workloads and explore track-specific differences. Two groups of healthy Indian soldiers (n=43 and 30; similar age, height, and weight) participated in time-bound 2.4 km runs on the jungle and flat natural tracks. Physiological variables, speed, and elevation with environmental parameters like temperature and humidity were recorded throughout the exercises. Subjective responses through NASA-TLX questionnaires were collected after the exercises. Mann-Whitney ‘U’ test was applied to find out the level of significance between groups.Physiological demands of runs on the jungle and flat natural track were similar (heart rate- 178.9 and 178.4 b/min; breathing rate- 42.0 and 46.6 breaths/min respectively; body temperature- 37.6℃ for both groups). The run on the jungle track needed a lower peak acceleration of 2.5 g (2.9 g on the flat track) and a higher variation in speed (4-16 knots). Participants expressed significantly high responses after the run on the jungle track. Run on the jungle track was physically intense, required adjustments in speed and acceleration to negotiate with the natural obstacles like uneven terrain and slippery surfaces. Besides this, environmental heat and higher humidity probably led to an increase in mental workload. The run on the flat natural track needed steady physical effort, fewer mechanical adjustments, and showed lower subjective responses.

Tuberculosis (TB) causes maximum mortality and morbidity worldwide. 25 per cent of the global population harbour Mycobacterium tuberculosis (Mtb) and therefore are at risk of developing active disease. Of late, the disseminated diseases of TB are on the increase. Nearly one-third of all TB infections can be classified as extrapulmonary-TB (EPTB). TB can spread to the bone, brain, intestine, peritoneum, genitourinary system, and female genital sites leading to problems of conception. Therefore undoubtedly, TB has turned out to be a tremendous public health problem globally. The emergence of drug-resistant bacteria calls for new anti-tuberculous drugs to enhance response to antimicrobial therapy for active TB. However, discoveries of very effective anti-TB new medicines have not materialised yet. Thus, nutritional anti-TB intervention is highly important. In the pre-antibiotic era, Vitamin D was used for the treatment of TB. Its active component 1,25-dihydroxy-vitamin D3 was shown to display anti-TB activity in vitro. Vitamin D deficient humans display greater susceptibility to TB. Vitamin D deficiency induces worse disease progression in TB cases as observed in many clinical trials. The efficacy of the addition of vitamin D supplements in TB treatment has also been estimated. Thus, by now, the role of vitamin D in TB prevention and treatment is well established. Knowledge of the molecular mechanism of vitamin D is crucially vital for new anti-TB drug design. This review article discusses the recent advancement regarding the molecular mechanism of vitamin D-related anti-TB action. Further elucidation of this area may help novel anti-TB drug development.

The depleting petroleum reserve, as well as increasing demand for crude oil, has attracted the research interest for alternative sources of energy. The surplus lignocellulosic biomass such as forest residues, crop residues, and weeds may be a potential source to derive biofuel by the thermochemical route. Gasification is an established technology for the utilization of biomass to obtain producer gas containing mainly H2 and CO as combustibles. The air-blown biomass gasifiers are widely installed where the resulting producer gas contains 55-60 per cent nitrogen and a lower percentage of H2 and CO with an H2/CO ratio of less than one. Gasification of lignocellulosic biomass using steam as an oxidant produces syn-gas with a lower amount of nitrogen, a higher percentage of hydrogen, and H2/CO > 2.1. Steam as an oxidant favors water gas shift reaction with the formation of hydrogen and enhances the H2/CO ratio. The ratio of steam to biomass was 1.20-1.25 so the water gas shift reaction and steam reforming of methane occur. The percentage of hydrogen in the syngas obtained by gascification of pine needles, camelina straw and Lantana biomass was 56.8, 68.7, and 72.8 per cent respectively. The present article describes the steam gasification of pine needle biomass, crop residue from Camelina sativa, and biomass from weed i.e. Lantana camara to produce syngas with a higher H2/CO ratio along with a high calorific value compared to the one with air-blown gasification.

From the ancient period, humans have been fighting pathogenic microorganisms for survivalpurposes and in this context, man has developed antibiotics as a powerful weapon to treat various infections caused by pathogens. Nevertheless, the need to discover new antimicrobial agents is increasing at an alarming rate. This is because the microorganisms have developed various mechanisms to resist the action of antibiotics. One such mechanism is the production of biofilm. Infections caused by biofilm-forming pathogenic microorganisms are very difficult to treat, even using potent antibiotics. However, in folk medicine, many plants are found to be helpful to treat certain infectious diseases. This is because of the synthesis of a variety of bioactive compounds by plants with high medicinal value. Hence, in the present study, three different plants were used viz Aegle marmelos, Picrorrhiza kurroa, and Swertia chirayita to determine their antioxidant and anti-quorum sensing activities. According to the literature, antioxidants delay the oxidation process and nullify the effect of free radicals that cause damage and accelerate aging. Quorum sensing is the chemical way of communication between biofilm-forming microorganisms. Among the alcoholic extracts, the methanolic extract of P. kurroa showed the highest DPPH radical scavenging activity of 82.11%. All the plant extracts under investigation exhibited anti-quorum sensing activity against the standard culture of Chromobacterium violaceum MTCC 2656; however, the plant extracts of A. marmelos were found to be more potent as compared to P. kurroa and S. chirayita. Plant extracts P. kurroa and S. chirayita showed almost similar anti-quorum sensing activity. This confirms the pharmaceutical importance of plant materials of interest, which might prove to be useful to treat damage caused by free radicals and biofilm-related infections, after due consideration of clinical trials for safety issues.

Radiation-induced genomic instability always remains a major concern for the medical society, following radiation exposure. Hence, development of a safe and effective radioprotector is of considerable interest in case of radiotherapy and radiation emergencies. Quercetin-3-Rutinoside (Q-3-R), a naturally occurring bioflavonoid, has shown promising potential against radiation injuries. The present study reports anti-genotoxic potential of Q-3-R against lethal (9Gy) dose of ionizing radiation. The mice were injected intramuscularly with Q-3-R (10mg/kg b.wt.), 1hr prior to lethal dose of radiation and dissected at 24hrs post treatment. Different kinds of chromosomal aberrations, micronuclei as well as pulverized metaphase and polyploidy were scored in bone marrow cells. Irradiated mice showed significantly (p<0.001) increased number of double minutes, fragments, dicentrics, rings, gaps and end to end association. Pulverized metaphases and polyploidy were also found to be elevated in irradiated group. Pretreatment of Q-3-R significantly countered these radiation-induced genetic variations in lethally exposed mice. Data from the present study support the anti-genotoxic potential of Q-3-R even at lethal dose of radiation. Q-3-R, possessing various pharmacological activities and being a safe supplement for treatment of other ailments, can be further explored for its radioprotective potential.

The reduction and stabilisation of fractured bone fragments have always been a challenging task for thesurgeon. A micro-platesystem for maxillofacial fracture treatment provides excellent results. However, plates and screws are difficult toadapt to the thin bone, and small fragments often lead to the weakening of bone causing secondary fractures. Surgical bone adhesives promise as a viable alternative for issues with micro-plates, but a lotremains desired for successful usefor clinical application. The present systematic review aims to identify the bone adhesive materials available at various stages in animal or human models in the last decade and enumerate their characteristics for potential use in non-load bearing maxillofacial fractures. PubMed electronic database searched using a combination of keywords to identify English language articles between January 2011 and December 2020 yielded a total of 1204 records, of which 15 were included for final review after applying PRISMA guidelines. Cyanoacrylate was the commonly used adhesive material followed by fibrin glue and calcium phosphate-based materials. Although encouraging, results with each material still lack human randomised control trials thus presenting inconclusive evidence. Studies on these lines are suggested along with the development of newer materials to overcome the shortcomings in the currently available systems.

Leaves of Lysimachia ramosa are used by various tribes of Meghalaya to cure intestinal helminth infections. Preliminary investigations disclosed impressive anthelmintic effects of the kaempferol derivative, an active component of the plant, however, toxic effects on its consumers, if any, are not known. Therefore, the present study has been undertaken to investigate the acute and sub-acute toxic effects of kaempferol derivative, of the plant, taking Wistar rats as a model. Following OECD 407, 250 mg, 500 mg, and 1000 mg/kg body weight doses of the active component have been selected to treat the animals for 28 days. On the 29th day, the animals have been sacrificed to assess different toxicological effects on animals. The LD50 value of the anthelmintic component was found to be more than 5000 mg/kg body weight of rats. Histological, ultrastructural, haematological, biochemical, andorgano-somatic (HSI and RSI) studies demonstrate changes in surface characteristics of various cellular organelles of different vital organs such as the liver, kidney, and intestine. Alterations were also recorded in different vital enzymes such as AST, ALT, and ALP in the phytochemical exposed rats at higher doses. The results revealed that treatment with the active component at a higher concentration may lead to toxicological effects if treatment persists for a longer period.

Maharashtra government reported 10,000 crore production loss of Pomegranate every year, due to the incidence of Telya disease. The present study was aimed to analyse the physical, chemical properties, and available micro-macronutrients in the soil of pomegranate orchards infected with Telya disease. Estimation of incidence and severity of disease was done on fifty selected orchards from different villages that were MangiTungi, Daswel, Dasane, Mulher, and Sompur. Results revealed that minimum incidence (58.66%) and severity (59.89%) were recorded in Sompur village whereas maximum incidence (74.40%) and severity (68.70%) were recorded in Daswel and MangiTungi village respectively. The pH (7.5-7.9) and free lime concentration 7.4-9.4%) were exceptionally very high for all test and control samples. Deficiency of essential macronutrients N (<150-250 Kg/ha) and K (<125-200 Kg/ha) was recorded in all test samples along with additional deficiency of Zn micronutrient (<1.0-2.0 ppm). In the case of mock orchards, all the parameters were in accordance with reference values.Statistical analysis of data declared that there was a significant difference among parameters of tested groups (P>0.05) while for control fields there were no significant differences (P<0.05). Further, a positive correlation between macro-micronutrients (Na, Ca, N, P, K, Mn) and incidence of disease was recorded which concludes that an imbalance in nutrients promotes growth of pathogens and increases susceptibility of plants to pathogenic attack. Further, balancing nutrients through fertilisers or foliar spray could be an effective strategy for an integrated pest management system.

Rhodiola imbricata is a high value medicinal plant of trans-Himalayan mountain passes in Ladakh. This plant is a highly sought after in national and international herbal product market due to its unique phytochemical composition and resultant medicinal properties. However, compositional variation in the raw material from different geographical locations results in variation in quality as well as efficacy of the final products. The current study was designed to generate the comparative GC-MS profiles of hydro-methanolic extracts of Rhodiola imbricata root samples collected from various locations in Ladakh i.e., Chang La (17605 ft), Khardung La (18,379 ft), and Shashi La (13908 ft) mountain passes. The study highlighted variations in volatile phytochemical composition in root samples collected from different locations, especially with respect to phenols, terpenes and fatty acids. Samples from Chang La had maximum amount of phenolic compounds (96.78 per cent), followed by samples from Khardung La (77.05 per cent) while they were undetected in samples from Shashi La pass. Specifically, comparative GC-MS profiling revealed that peak area percentage of two important bioactive compounds (i.e. piceol and apocynin) varied amongst samples. In the samples collected from Chang La, the piceol covered (94 per cent) and apocynin covered (2.78 per cent) peak area whereas in samples collected from Khardung La, piceol covered (73.8 per cent) and apocynin covered (3.25 per cent) peak areas respectively, however, samples collected from Shashi La showed none of these compounds. Interestingly, in the present study, apocynin (a potent NADPH oxidase inhibitor) is being reported for the first time from Rhodoila genus. On the basis of present findings, samples collected from Chang La and Khardung La passes showed better phytochemical composition of pharmacological active phenolic compounds than Shashi La sample.
叠瓦红景天是拉达克跨喜马拉雅山口的一种高价值药用植物。这种植物因其独特的植物化学成分和由此产生的药用特性而在国内外草药产品市场上备受追捧。然而，来自不同地理位置的原材料的成分变化会导致最终产品的质量和功效的变化。目前的研究旨在生成从拉达克不同地点（即昌拉（17605英尺）、哈尔东拉（18379英尺）和沙什拉（13908英尺）山口采集的叠瓦红景天根样品的水-甲醇提取物的比较GC-MS图谱。该研究强调了从不同地点采集的根样品中挥发性植物化学成分的变化，特别是酚类、萜烯类和脂肪酸。Chang La样品中酚类化合物含量最高（96.78%），其次是Khardung La样品（77.05%），而Shashi La pass样品中未检测到酚类化合物。特别是，比较GC-MS分析显示，两种重要生物活性化合物（即苦辛和罗布麻）的峰面积百分比在样品之间存在差异。在昌拉采集的样品中，苦味素覆盖（94%）和罗布麻素覆盖（2.78%）的峰面积，而在哈尔东拉采集的样本中，苦味素覆盖（73.8%）和罗布麻素覆盖的峰面积分别为3.25%，但在沙市拉采集的样品中没有显示这些化合物。有趣的是，在本研究中，罗布麻素（一种强效NADPH氧化酶抑制剂）首次从红油属植物中被报道。根据目前的研究结果，从昌拉和哈尔东拉山口采集的样品显示出比沙市拉样品更好的药理活性酚类化合物的植物化学组成。

Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) has caused the greatest worldwide pandemic called Coronavirus-2019 (COVID-19) disease. The SARS-CoV-2 virus primarily attacks the respiratory tract, but it also disturbs the gastrointestinal system (GIT). The presence of the angiotensin-converting enzyme-2 (ACE-2) receptor in the intestinal epithelial cells, suggest the transmission of SARS-CoV-2 viruses from lungs to gut through systemic circulation. The virus detected in fecal samples of COVID-19 patients causes several gastrointestinal maladies including vomiting, diarrhea, and pain in abdomen. The gastrointestinal symptoms are associated with alterations in gut microbial composition, an increase in inflammatory cytokines and delayed virus clearance. Several studies demonstrated a decreased abundance of beneficial microbial species and increased opportunistic pathogens in the fecal samples of COVID-19 patients. The gut and lungs, share a bi-directional relationship called the “gut-lung axis” which is modulated by imbalanced gut microbiota. Since the gut microbes are suggested to play a vital role in health and disease by maintaining homeostasis of the immune system, therefore targeting the intestinal dysbiosis with beneficial microbial species, seems plausible to eventually diminish the effects of pulmonary infections and diseases. In this review, we have summarized studies demonstrating the gut-lung axis in association with gut dysbiosis in COVID-19 patients. In addition, the review also highlights the studies showing the potential role of probiotic supplementation in the amelioration of various respiratory infections and diseases. Data demonstrate that the restoration of gut microbial communities by probiotic supplementation can enhance lung capacity to combat respiratory viral infections including SARS-CoV-2.
