The aim of the study was the assessment of hematological parameters in pulmonary tuberculosis patients. Forty patients diagnosed with tuberculosis were recruited from the Institute of Thoracic Medicine on the basis of history, clinical examination, chest radiography, sputum examination and related laboratory parameters and were compared with age and sex matched healthy volunteers (n = 40). Hematological parameters and CRP in tuberculosis patients were determined. The mean values for serum hemoglobin level, RBC count and platelet count in PTB was found to be less (p \ 0.001). Erythrocyte sedimentation rate (ESR), plasma C-reactive protein, WBC count in PTB subjects was increased (p \ 0.001 for ESR & CRP, p \ 0.05 for WBCs) and all were statistically significant. This study demonstrated that serum hemoglobin level, RBC count and platelet count was decreased in tuberculosis patients whereas ESR, CRP and WBC count was increased when compared with healthy controls.

Parkinson's disease (PD), a neurodegenerative disorder characterized by distinct aging-independent loss of dopaminergic neurons in substantia nigra pars compacta (SNpc) region urging toward neuronal loss. Over the decade, various key findings from clinical perspective to molecular pathogenesis have aided in understanding the genetics with assorted genes related with PD. Subsequently, several pathways have been incriminated in the pathogenesis of PD, involving mitochondrial dysfunction, protein aggregation, and misfolding. On the other hand, the sporadic form of PD cases is found with no genetic linkage, which still remain an unanswered question? The exertion in ascertaining vulnerability factors in PD considering the genetic factors are to be further dissevered in the forthcoming decades with advancement in research studies. One of the major proponents behind the prognosis of PD is the pathogenic transmutation of aberrant alpha-synuclein protein into amyloid fibrillar structures, which actuates neurodegeneration. Alpha-synuclein, transcribed by SNCA gene is a neuroprotein found predominantly in brain. It is implicated in the modulation of synaptic vesicle transport and eventual release of neurotransmitters. Due to genetic mutations and other elusive factors, the alpha-synuclein misfolds into its amyloid form. Therefore, this review aims in briefing the molecular understanding of the alpha-synuclein associated with PD.

Zinc (Zn), the second-most necessary trace element, is abundant in the human body. The human body lacks the capacity to store Zn; hence, the dietary intake of Zn is essential for various functions and metabolism. The uptake of Zn during its transport through the body is important for proper development of the three major accessory sex glands: the testis, epididymis, and prostate. It plays key roles in the initial stages of germ cell development and spermatogenesis, sperm cell development and maturation, ejaculation, liquefaction, the binding of spermatozoa and prostasomes, capacitation, and fertilization. The prostate releases more Zn into the seminal plasma during ejaculation, and it plays a significant role in sperm release and motility. During the maternal, labor, perinatal, and neonatal periods, the part of Zn is vital. The average dietary intake of Zn is in the range of 8–12 mg/day in developing countries during the maternal period. Globally, the dietary intake of Zn varies for pregnant and lactating mothers, but the average Zn intake is in the range of 9.6–11.2 mg/day. The absence of Zn and the consequences of this have been discussed using critical evidence. The events and functions of Zn related to successful fertilization have been summarized in detail. Briefly, our current review emphasizes the role of Zn at each stage of human reproduction, from the spermatogenesis process to childbirth. The role of Zn and its supplementation in in vitro fertilization (IVF) opens opportunities for future studies on reproductive biology.

Our study was aimed to assess the levels of serum calcium and phosphorus in pulmonary tuberculosis patients. Blood samples were collected from 40 patients with pulmonary tuberculosis before treatment (PTB-0), at the end of 2 months of intensive phase of treatment (PTB-2) and after 6 months of treatment (PTB-6). Age and weight matched normal healthy volunteers (n = 37) served as normal controls. Serum was analyzed for calcium and phosphorus. Serum calcium significantly decreased to hypocalcemic levels and serum phosphorus significantly decreased but was within normophosphatemic limits in pulmonary tuberculosis. Chemotherapy for tuberculosis managed to raise serum levels of both the ions, with hypocalcemia still persisting in majority of patients during treatment but getting resolved in a significant percentage of patients at the end of 6 months of treatment. Results indicate the need for calcium and phosphorus supplements in tuberculosis patients during chemotherapy. This study also warrants the need for regular monitoring of serum calcium and phosphorus in patients undergoing anti-tuberculosis treatment.

Mutations in human laforin lead to an autosomal neurodegenerative disorder Lafora disease. In N-terminal carbohydrate binding domain of laforin, two mutations W32G and K87A are reported as highly disease causing laforin mutants. Experimental studies reported that mutations are responsible for the abolishment of glycogen binding which is a critical function of laforin. Our current computational study focused on the role of conformational changes in human laforin structure due to existing single mutation W32G and prepared double mutation W32G/K87A related to loss of glycogen binding. We performed 10 ns molecular dynamics (MD) simulation studies in the Gromacs package for both mutations and analyzed the trajectories. From the results, the global properties like root mean square deviation, root mean square fluctuation, radius of gyration, solvent accessible surface area and hydrogen bonds showed structural changes in atomic level observed in W32G and W32G/K87A laforin mutants. The conformational change induced by mutants influenced the loss of the overall stability of the native laforin. Moreover, the change in overall motion of protein was analyzed by principal component analysis and results showed protein clusters expanded more than native and also change in direction in case of double mutant in conformational space. Overall, our report provides theoretical information on loss of structure-function relationship due to flexible nature of laforin mutants. In conclusion, comparative MD simulation studies support the experimental data on W32G and W32G/K87A related to the lafora disease mechanism on glycogen binding.
