Zika virus (ZIKV), member of the family Flaviviridae belonging to genus Flavivirus, is an arthropod-borne virus. The ZIKV is known to cause severe congenital birth defects in neonates. Due to a large number of worldwide outbreaks and associated neurological complications with ZIKV, a public health emergency was declared by the World Health Organization on February 1, 2016. ⋯ The virus modulates cell machinery at several levels to replicate itself and inhibits toll like receptors-3 signalling, deregulates microRNA circuitry and induces a chronic inflammatory response in affected cells. Several significant advances have been made to understand the mechanisms of neuropathogenesis, its prevention and treatment. The current review provides an update on cellular and molecular mechanisms of ZIKV-induced alterations in the function of various brain cells.

Osteoarthritis (OA) is the 11th leading cause of disability in the modern world, but till date, there have been no effective markers for monitoring the progression of OA. The three proteins RANK/RANK-Ligand and Osteoprotegerin (OPG) have been found to be the key regulators of bone metabolism. Interaction of RANK-Ligand with its receptor RANK triggers differentiation of osteoclasts leading to bone resorption. OPG on the other hand is protective as it is expressed by osteoblasts and bind RANKL with higher affinity preventing its interaction with RANK. The levels of these serum proteins are regulated by vitamin D and parathyroid hormones. Therefore, the present study, aimed to study the association of serum RANKL, OPG and vitamin D with disease severity in patients with knee OA. ⋯ Overall the results suggest that OPG may be considered as an early marker of the diseases.

Gastric mucosa-associated lymphoid tissue (MALT) lymphoma is a common marginal zone lymphoma. The stomach is the relatively common origin of the MALT lymphoma, now termed as extranodal marginal zone B-cell lymphoma. Gastric MALT lymphoma has good prognosis due to clinical response to treatment and favourable overall survival. In this study, clinical characteristics and treatment of patients of early gastric MALT lymphoma were retrospectively analysed. ⋯ For patients with early gastric MALT lymphoma, anti-H. pylori treatment may be effective. Patients with poor results of anti-H. pylori treatment need to be treated with anti-tumour therapy.

A etiologically symmetric and asymmetric small for gestational age (SGA) infants are two distinct entities. In view of absence of longitudinal information on growth pattern of skinfold thicknesses (SFTs) among Indian infants, this study was conducted to assess the auxological dynamics of SFTs (sub-cutaneous fat) of symmetric and asymmetric SGA infants. ⋯ Thinner SFTs obtained for symmetric and asymmetric SGA as compared to AGA infants reveal their compromised adiposity and nutritional status. Comparatively, higher SFTs in symmetric than in asymmetric SGA infants appear to suggest that the former have a tendency to accumulate more fat, than the latter during infancy.
