RESUMO

We derive an expression for the energy-momentum tensor in the discrete lattice formulation of pure glue QCD. The resulting expression satisfies the continuity equation for energy conservation up to numerical errors with a symmetric procedure for the time discretization. In the case of the momentum conservation equation, we obtain an expression that is of higher accuracy in lattice spacing (O(a2)) than the naive discretization where fields in the continuum expressions are replaced by discretized counterparts. The improvements are verified by performing numerical tests on the derived expressions using classical real-time lattice gauge theory simulations. We demonstrate substantial reductions in relative error of one to several orders of magnitude compared to a naive discretization for both energy and momentum conservation equations. We expect our formulation to have applications in the area of pre-equilibrium dynamics in ultrarelativistic heavy ion collisions, in particular for the extraction of transport coefficients such as shear viscosity.

RESUMO

The Phyllanthus genus is very important plant traded as a raw herbal medicine in India. Commonly known as 'Bhumyamalaki' (Phyllanthus species) has been used for the prevention and treatment of jaundice. Phyllanthus is rich in diversity of bioactive compounds such as lignans, alkaloids, terpenoids, flavonoids, and tannins. Among some metabolites such as phyllanthin, hypophyllanthin, 8, 9-epoxy brevifolin, brevifolin, quercetin, gallic acid, elagic acid, and brevifolin carboxylate have been shown to have hepatoprotective and antioxidant activity found in this genus. The basic objective of this review was to overview the hepatoprotective activity based on the other available data from various plants of the Phyllanthus species including Phyllanthus amarus, Phyllanhtus urinaria, Phyllanthus fraternus, Phyllanthus maderaspatenis, Phyllanthus simplex, Phyllanthus emblica, Phyllanthus debillis, Phyllanthus tenellus, Phyllanthus polyphyllus, Phyllanthus reticulates, Phyllanthus indofischerii, Phyllanthus acidus, Phyllanthus niruri, Phyllanthus rheedii, Phyllanthus kozhikodianus, and Phyllanthus longiflorus. These species studied had considerable hepatoprotective potential. The secondary data, each in vitro and in vivo studies confirm the capacity of Phyllanthus species used as a remedy for jaundice or liver disease in addition to having antioxidants. Furthermore, it could be concluded that herbal drugs have the least side effects and are taken into considered safe for human health, they are able to substantially alternative synthetic drugs in the future.

RESUMO

Bawri or Garri, a non-descript cattle population managed under an extensive system in Madhya Pradesh state of India, was identified and characterized both genetically and phenotypically to check whether or not it can be recognised as a breed. The cattle have white and gray colour and are medium sized with 122.5 ± 7.5 cm and 109.45 ± 0.39 cm height at withers in male and female, respectively. Double-digest restriction site associated DNA (ddRAD) sequencing was employed to identify ascertainment bias free SNPs representing the entire genome cost effectively; resulting in calling 1,156,650 high quality SNPs. Observed homozygosity was 0.76, indicating Bawri as a quite unique population. However, the inbreeding coefficient was 0.025, indicating lack of selection. SNPs found here can be used in GWAS and genetic evaluation programs. Considering the uniqueness of Bawri cattle, it can be registered as a breed for its better genetic management.

RESUMO

Nitrogen (N) and phosphorus (P) are vital for crop growth. However, most agricultural systems have limited inherent ability to supply N and P to crops. Biochars (BCs) are strongly advocated in agrosystems and are known to improve the availability of N and P in crops through different chemical transformations. Herein, a soil-biochar incubation experiment was carried out to investigate the transformations of N and P in two different textured soils, namely clay loam and loamy sand, on mixing with rice straw biochar (RSB) and acacia wood biochar (ACB) at each level (0, 0.5, and 1.0% w/w). Ammonium N (NH4-N) decreased continuously with the increasing incubation period. The ammonium N content disappeared rapidly in both the soils incubated with biochars compared to the unamended soil. RSB increased the nitrate N (NO3-N) content significantly compared to ACB for the entire study period in both texturally divergent soils. The nitrate N content increased with the enhanced biochar addition rate in clay loam soil until 15 days after incubation; however, it was reduced for the biochar addition rate of 1% compared to 0.5% at 30 and 60 days after incubation in loamy sand soil. With ACB, the net increase in nitrate N content with the biochar addition rate of 1% remained higher than the 0.5% rate for 60 days in clay loam and 30 days in loamy sand soil. The phosphorus content remained consistently higher in both the soils amended with two types of biochars till the completion of the experiment.

RESUMO

A survey for slug- and snail-associated nematodes was conducted in forests, parks, botanical gardens, and nature reserves at 13 localities in Belgium to uncover more diversity of gastropod mollusc-associated nematodes and to characterise Pellioditis populations found in the country. A total of 319 slugs and snails belonging to nine species were examined. Arion vulgaris was the most commonly found mollusc species in this study (eight locations), and 19.4% of the examined mollusc specimens were found infected by nematodes. The highest prevalence of nematodes was observed in Cornu aspersum (60%) followed by A. vulgaris (34.8%), Limax maximus (28.6%), and Cepaea sp. (20%). Eleven nematode species belonging to eight families were isolated and identified from the mollusc hosts including Alloionema appendiculatum, Angiostoma dentiferum, A. gandavense, Angiostrongylus vasorum, Cosmocerca longicauda, Panagrolaimus cf. subelongatus, Pellioditis californica, P. hermaphrodita, Rhabditis sp., Tetrameres cf. fissispina, and Troglostrongylus cf. brevior.Pellioditis was the most commonly found nematode genus (at nine localities) and C. longicauda and P. californica were reported in Belgium for the first time. Co-infections of more than one nematode species were observed in eight (2.5%) molluscs specimens. Most co-infections consisted of two nematode species. In one A. vulgaris specimen, a co-infection of three nematode species (A. vasorum, P. hermaphrodita, and Tetrameres cf. fissispina) was observed. Four ex vivo cultures of P. californica and six ex vivo cultures of P. hermaphrodita were established from single hermaphrodites, and both species were described based on light microscopy, scanning electron microscopy, and morphometric, morphological, and molecular data.

RESUMO

In the plains of western North India, traditional rice and wheat cropping systems (RWCS) consume a significant amount of energy and carbon. In order to assess the long-term energy budgets, ecological footprint, and greenhouse gas (GHG) pollutants from RWCS with residual management techniques, field research was conducted which consisted of fourteen treatments that combined various tillage techniques, fertilization methods, and whether or not straw return was present in randomized block design. By altering the formation of aggregates and the distribution of carbon within them, tillage techniques can affect the dynamics of organic carbon in soil and soil microbial activity. The stability of large macro-aggregates (> 2 mm), small macro-aggregates (2.0-2.25 mm), and micro-aggregates in the topsoil were improved by 35.18%, 33.52%, and 25.10%, respectively, over conventional tillage (0-20 cm) using tillage strategies for conservation methods (no-till in conjunction with straw return and organic fertilizers). The subsoil (20-40 cm) displayed the same pattern. In contrast to conventional tilling with no straw returns, macro-aggregates of all sizes and micro-aggregates increased by 24.52%, 28.48%, and 18.12%, respectively, when conservation tillage with organic and chemical fertilizers was used. The straw return (aggregate-associated C) also resulted in a significant increase in aggregate-associated carbon. When zero tillage was paired with straw return, chemical, and organic fertilizers, the topsoil's overall aggregate-associated C across all aggregate proportions increased. Conversely, conventional tillage, in contrast to conservation tillage, included straw return as well as chemical and organic fertilizers and had high aggregate-associated C in the subsurface. This study finds that tillage techniques could change the dynamics of microbial biomass in soils and organic soil carbon by altering the aggregate and distribution of C therein.

RESUMO

Utilizing available water resources efficiently is crucial to address both our present and future requirements and plays a vital role in safeguarding food security. This current investigation deals with assessment and optimizing water footprint (WF) and virtual water flow (VWF) for primary crops in Banas River Basin (BRB) using AquaCrop model with local datasets and district-level estimates. VWF in the basins were estimated by multiplying the WF of crops with the amount exported/imported, which is determined based on the difference between production and consumption in the basin. The possibility of changing the cropping patterns was evaluated for the potential reduction of the blue WF. Annual WF from primary crops in the basin amounts to 19,255 MCM/yr (70 % green, 21 % blue and 10 % grey WF, respectively). Banas basin is a net exporter of agriculture commodities with nearly 7391 MCM/yr of water flowing out of the basin due to agricultural exports of which approximately 265 MCM/yr is virtual blue water outflow. Crops having low economic water productivity of blue water are being grown in vast areas resulting in a high blue WF. The optimizing the cropping pattern can result in a 5-42 % lower blue water footprint with 11-39 % higher economic output under different scenarios with and without considering the consumption needs. Changing the cropping pattern and making trade plan to optimize the crop import/exports can be viable option for tackling the blue water scarcity issues in the basin. WF can be managed sustainably by improving water resource allocation for better economic, social, and environmental productivity and going for less aggressive agricultural production.

RESUMO

A number of theoretical models have been developed in recent years modelling epidemic spread in educational settings such as universities, often as part of efforts to inform re-opening strategies during the COVID-19 pandemic. However, these studies have had differing conclusions as to the most effective non-pharmaceutical interventions. They also largely assumed permanent acquired immunity, meaning we have less understanding of how disease dynamics will play out when immunity wanes. Here, we complement these studies by developing and analysing a general stochastic simulation model of disease spread on a university campus where we allow immunity to wane, exploring the effectiveness of different interventions. We find that the two most effective interventions to limit the severity of a disease outbreak are reducing extra-household mixing and surveillance testing backed-up by a moderate isolation period. We find that contact tracing only has a limited effect, while reducing class sizes only has much effect if extra-household mixing is already low. We identify a range of measures that can not only limit an outbreak but prevent it entirely, and also comment on the variation in measures of severity that emerge from our stochastic simulations. We hope that our model may help in designing effective strategies for universities in future disease outbreaks.

RESUMO

Lutetium-177 radio-pharmaceutical has become an important theranostic candidate in cancer treatment. Its availability from bench-to-bed requires strategic implementation of isotope-enrichment, neutron-irradiation and radio-chemical techniques. In this paper, the need for enrichment of lutetium-176 is emphasized by estimating specific activity of lutetium-177 as a function of enrichment percentage for typical neutron flux available at Dhruva reactor, India. A novel Atomic Vapour Laser Isotope Separation (AVLIS) module for lutetium-176 enrichment is designed to meet the above requirement. The paper documents its characteristics and production estimates. The design is carried out after critical assessment and evaluation of available AVLIS-infrastructure in the country. Outline of lutetium-177 enrichment, capable of producing non-carrier-added lutetium is also provided. This work concludes that India has taken a step forward towards self-reliance (Atmanirbhar Bharat) in securing the supply chain of lutetium-177.

RESUMO

Subcutaneous emphysema is a condition when air or gas gets trapped within the subcutaneous layer. It is characterised by crackling feeling on palpation of the skin known as subcutaneous crepitation which is described as touching rice krispies. A 70 years male from hilly region of Nepal with agricultural background suffered multiple injuries sustained due to an attack by domesticated bull in his house. Upon the incident the injured male was taken to hospital, where he was declared "Brought Dead" by the Emergency Department of Dhulikhel Hospital, Kathmandu University Hospital. His body was brought for autopsy in Department of Forensic Medicine and Toxicology of Kathmandu University School of Medical Sciences. On complete autopsy, massive subcutaneous emphysema and pneumothorax was demonstrated. The details of finding are discussed in detail as follows.

RESUMO

Multicellular organisms are constantly subjected to pathogens that might be harmful. Although insects lack an adaptive immune system, they possess highly effective anti-infective mechanisms. Bacterial phagocytosis and parasite encapsulation are some forms of cellular responses. Insects often defend themselves against infections through a humoral response. This phenomenon includes the secretion of antimicrobial peptides into the hemolymph. Specific receptors for detecting infection are required for the recognition of foreign pathogens such as the proteins that recognize glucans and peptidoglycans, together referred to as PGRPs and ßGRPs. Activation of these receptors leads to the stimulation of signaling pathways which further activates the genes encoding for antimicrobial peptides. Some instances of such pathways are the JAK-STAT, Imd, and Toll. The host immune response that frequently accompanies infections has, however, been circumvented by diseases, which may have assisted insects evolve their own complicated immune systems. The role of ncRNAs in insect immunology has been discussed in several notable studies and reviews. This paper examines the most recent research on the immune regulatory function of ncRNAs during insect-pathogen crosstalk, including insect- and pathogen-encoded miRNAs and lncRNAs, and provides an overview of the important insect signaling pathways and effector mechanisms activated by diverse pathogen invaders.

RESUMO

BACKGROUND: Post-dural puncture headache (PDPH) is a well-documented complication of accidental dural puncture in obstetric patients. Reports have shown successful treatment with adrenocorticotropic hormone (ACTH) but evidence remains low and limited. In this retrospective analysis, we assessed whether prophylactic administration of cosyntropin, a synthetic derivative of ACTH, reduced the incidence of PDPH after accidental dural puncture in parturients. METHOD: The study population included 132 women with an accidental dural puncture over a three-year period (June 1, 2018 to Oct 31, 2021) at a large tertiary-care center. Patient electronic medical records were reviewed for patient characteristics, prophylactic administration of cosyntropin, PDPH diagnosis, and need for epidural blood patch. Typically, 1 mg of cosyntropin was administered as an intravenous bolus or infusion post-delivery. The propensity score was calculated based on the following factors: age, body mass index, and placement of an intrathecal catheter. Patients were matched allowing 10% variation in scores to reduce potential treatment assignment bias. RESULTS: A total of 115 patients were included in the final analysis. Intravenous cosyntropin was administered to 65 patients (55.6%). Among those who received cosyntropin, 37 (56.9%) developed PDPH compared with 29 patients (58%) in the no-cosyntropin group (P = 0.08). Epidural blood patch was performed in 21 patients (56.8%) who received cosyntropin and 13 patients (61.7%) who did not (P = 0.70). CONCLUSION: Prophylactic administration of cosyntropin is not associated with a reduced incidence of PDPH.

RESUMO

Oxytocin is widely used to prevent atonic postpartum haemorrhage after caesarean delivery. Initial treatment failure rates are high and inadequate dosing may contribute. Excessive doses, however, are associated with serious adverse effects. The pharmacokinetic data from this context are sparse and there is a lack of data in the immediate postpartum minutes after an initiating bolus. The pharmacodynamic data from this context are exclusively from dose-effect studies, with some suggesting that higher doses of oxytocin are required to provide adequate uterine tone in obese compared with non-obese women. We aimed to perform a pharmacokinetic and pharmacodynamic study that would facilitate more precise weight-based oxytocin dosing. We measured arterial oxytocin concentration, uterine tone and haemodynamic parameters in 25 women in the first 40 min after exogenous oxytocin administration at elective caesarean delivery. Serum oxytocin concentrations varied considerably between individuals. We constructed a one-compartment pharmacokinetic model of exogenous oxytocin deposition, after its administration with an initiating bolus and a maintenance infusion, at elective caesarean delivery. Body weight was evaluated as a potential covariate but was not included in the model due to lack of statistically significant reduction in the objective function. We calculated the volume of distribution and clearance (mean [coefficient of variation]) as 156.1 l [18%] and 83 ml.s-1 [32%] but found no within-individual correlation between serum oxytocin concentration and uterine tone or haemodynamic parameters. In conclusion, we observed a large variation in serum oxytocin concentrations between individuals receiving similar doses of oxytocin and were unable to establish weight-based dosing of exogenous oxytocin at caesarean delivery. Our findings suggest that future studies on oxytocin pharmacokinetics would need large sample sizes. In the absence of such data, oxytocin dosing should continue to be guided by uterine tone assessments and adjusted according to a strategy based on the best evidence from dose-effect studies.

RESUMO

INTRODUCTION: The Desarda autologous tissue repair is comparable to the Lichtenstein hernioplasty for inguinal hernia regarding recurrence, chronic groin pain, and return to work activities. This study was designed to establish the outcomes of Desarda's repair versus Lichtenstein's hernioplasty concerning post-operative recovery to normal gait and its feasibility under local anesthesia (LA). MATERIALS AND METHODS: This study was a single-center, prospective, double-blinded, non-inferiority, randomized trial. Patients undergoing open hernia repair for primary inguinal hernia were included. Patients were randomly assigned and followed up for 2 years. The primary endpoint was the time to return to normal gait post-surgery with comfort (non-inferiority margin fixed as 0.5 days). The secondary outcomes studied were post-operative pain score, the time required to return to work (all previously performed activities), and surgical-site occurrences (SSO). RESULTS: One hundred ten eligible patients were randomly assigned [56 patients (50.9%) in the Desarda group and 54 patients (49.1%) in the Lichtenstein group]. All the procedures were safely performed under LA. The median (interquartile range) time for resuming gait post-surgery with comfort was 5 days in the Desarda vs 4 days in Lichtenstein's arm (P = 0.16), thereby failing to demonstrate non-inferiority of Desarda against Lichtenstein hernioplasty. However, there were no significant differences in days to return to work, SSO, chronic groin pain, and recurrence within two years of surgery. CONCLUSIONS AND RELEVANCE: This study could not demonstrate the non-inferiority of the Desarda repair versus Lichtenstein hernioplasty regarding the time taken to return to normal gait. Comparing the days to return to work, pain score, SSO, and chronic groin pain, including recurrence rate, Desarda repair faired equally with Lichtenstein hernioplasty, thereby highlighting its feasibility and efficacy under LA.

RESUMO

BACKGROUND: Severe perinatal depression is a significant cause of mortality and morbidity in neonates. Vitamin D levels were observed to be low in mothers and their neonates with hypoxic ischemic encephalopathy in some studies, owing to its neuroprotective properties. OBJECTIVE: Primary objective was to compare vitamin D deficiency state in full term neonates with severe perinatal depression and healthy term controls. Secondary objectives were to determine sensitivity and specificity of serum 25(OH)D<12 ng/mL in predicting mortality, development of hypoxic ischemic encephalopathy, abnormal neurological examination at discharge, and developmental outcome at 12 weeks of age. MATERIAL AND METHODS: Serum 25(OH)D levels in full term neonates with severe perinatal depression and healthy controls were compared. RESULTS: Serum 25(OH)D levels in severe perinatal depression and controls (n = 55 each group) were significantly different (7.50 ± 3.53 ng/mL vs 20.23 ± 12.70 ng/mL). At cut-off of < 12 ng/mL, serum 25(OH)D could predict mortality with 100% sensitivity and 17% specificity and poor developmental outcomes with sensitivity of 100% and specificity of 50%. CONCLUSION: Vitamin D deficiency status at birth can serve as an effective screening tool and poor prognostic markers in term neonates with severe perinatal depression.
