This paper explores a revelatory moment in fieldwork-the death of a close friend and research participant who died suddenly in suspicious circumstances. Her mourning period challenged my understandings of grief in Lihir. read more In a previous article I argued that grief in Lihir is resilient and focused on remembering and forgetting, rather than emotions. However this particular mourning period was an emotionally charged space and time. I explore what made this death and grief distinctive, arguing that the nature of her death provoked shock and anger. This paper contributes to an ongoing discussion about how sudden or violent deaths might impact grieving both in the local context, and globally.Hereditary spastic paraplegias (HSPs) are a diverse class of neurodegenerative disorders that mainly affect the corticospinal tract of the body and result in various clinical conditions such as lower limb spasticity and muscle weakness in the lower extremities. Worldwide, more than 70 chromosomal loci/genes have been reported to be associated with HSPs, out of which, six genes viz., ATL1, FA2H, GJC2, AP4E1, ALDH18A1 and ATP13A2 have been mapped in Pakistani families. In the present genetic study, we report on a large consanguineous Pakistani family with a complex form of HSP segregating with a 18 bp deletion in the first exon of the Fatty Acid 2-Hydroxylase (FA2H) gene (NM_024306.5c.159_176del). The identified in-frame deletion results in loss of six amino acids (p.Arg53_Ile58del) within the cytochrome B5 domain of the protein. FA2H is required for alpha-hydroxylation of free fatty acids to form alpha-hydroxylated sphingolipids. Its cytochrome b5-like heme-binding domain, which spans from residues 15 to 85, imparts the redox activity to FA2H. This mutation has previously been reported in a Pakistani family presenting with a similar form of complex HSP. Together with our findings the pathogenic role of the observed variant is further supported. Mutation studies on additional Pakistani families for FA2H will further elucidate its mutational spectrum, which may help in developing a prenatal diagnostic test for Khyber Pakhtunkhwa resident Pakistani families.The global emergence of novel coronavirus disease and its rapid global expansion over a short span of time require effective countermeasures to combat it. Development of a specific vaccine can induce an optimal antibody response, thus providing immunity against it. Our study proposes a detailed and comprehensive immunoinformatic approach that can be applied to the currently available coronavirus protein data in the online server for vaccine candidate development. We have identified the receptor binding domain (RBD) of structural spike protein (S1) as a potential target for immunity against COVID- 19 infection. Epitope prediction illustrated cytotoxic T-cell epitopes, helper T-cell epitopes, and B-cell epitopes associated with the target protein. These were joined through specific linkers along with adjuvant beta-defensin located at the N-terminal to create a multi epitope subunit vaccine (MESV). The specificity in the binding of the devised vaccine candidate to the TLR-3 immune cell receptor was evaluated via molecular docking interaction studies. Good docking score combined with robust interactions in the binding cavity certified the stringency of the engineered vaccine. Molecular dynamics simulation data showed minimal variation of the root-mean square deviations (RMSDs) and root-mean-square fluctuations (RMSFs) which confirmed the interaction stability. These results obtained from various in-silico experiments indicate the potency of this vaccine candidate as a probable therapeutic agent against COVID-19. Vaccination strategies targeting conserved epitope-based immune response would be beneficial in providing cross protection across beta-coronaviruses, and such vaccines would be resistant to the ever-evolving viruses.

We examined the IAT in 130 patients with depression and 125 healthy controls, along with self-reported suicidal ideation. IAT could differentiate patients with suicide attempts from patients without suicide attempts and controls. IAT measures were significantly correlated to explicit suicidal ideation and clinical symptoms in patients. Moreover, the IAT-symptom correlations were significant in female but not male patients. The IAT showed promise as a valid tool to estimate suicide risk in patients with depression and may be particularly useful in female patients.Scheper-Hughes divides mothers onto "better off" vis-à-vis "poor" mothers stuck in "old" reproductive strategy with high fertility. Cultural construction of mother love allows the latter group to neglect their "worst bets" to death without grief. Based on the bio-evolutionary theory, Hrdy hints that "modern" Western mothers, guided by ethical behavior, care for unviable infants while mothers in "non-Western societies" might dispose them of due to innate responses. This article warns against such binary division of mothers. Ethnographic research indicates that notions of replaceable infants, fatalism, appreciation of infant vitality, and lifesaving names are examples of human responses to adverse circumstances.Hepatitis C virus (HCV), which infected 71 million worldwide and about 5%-6% are from Pakistan, is an ssRNA virus, responsible for end-stage liver disease. To date, no effective therapy is available to cure this disease. Hence, it is important to study the most prevalent genotypes infecting human population and design novel vaccine or small molecule inhibitors to control the infections associated with HCV. Therefore, in this study clinical samples (n = 35; HCV-3a) from HCV patients were subjected to Sanger sequencing method. The sequencing of the core gene, which is generally considered as conserved, involved in the detection, quantitation and genotyping of HCV was performed. Multiple mutations, that is, R46C, R70Q, L91C, G60E, N/S105A, P108A, N110I, S116V, G90S, A77G and G145R that could be linked with response to antiviral therapies were detected. Phylogenetic analysis suggests emerging viral isolates are circulating in Pakistan. Using ab initio modelling technique, we predicted the 3D structure of core protein and subjected to molecular dynamics simulation to extract the most stable conformation of the structure for further analysis.
