Research Productivity of Saha Institute of Nuclear physics (SINP), India with special reference to International Collaborative Experimental Consortia

The Saha Institute of Nuclear Physics (SINP) is one of the prestigious autonomous research institutes under the Department of Atomic Energy, Govt. of India. The present study is carried out to identify the research performance of the scientists of SINP during 2005-2016. For this purpose, a total number of 3694 articles as reflected in Web of Science (WoS) database have been retrieved and evaluated on the basis of year, authorship, publication pattern, source journal, impact factor, collaborating institution, country, research area and citation. Out of total publications, the international collaborative research output constitute 41.20% share and western developed nations i.e. USA, Germany, Italy have been found as the most favoured countries for collaborations. The institute has produced significant number of research articles participating with international collaboration experimental groups or consortia like ALISC, CMS, MAGIC and PICASSO. The scientists of SINP also select some foreign reputed journals to publish their maximum research findings and of these, Physics Letters B journal has been found as the most preferred source journal

Three-dimensional kinematics of the human metatarsophalangeal joint during level walking

The objective of this study is to investigate the three-dimensional (3D) kinematics of the functional rotation axis of the human metatarsophanlangeal (MP) joint during level walking at different speeds. A twelve camera motion analysis system was used to capture the 3D motion of the foot segments and a six force plate array was employed to record the simultaneous ground reaction forces and moments. The 3D orientation and position of the functional axis (FA) of the MP joint were determined based on the relative motion data between the tarsometatarsi (hindfoot) and phalanges (forefoot) segments. From the results of a series of statistical analyses, it was found that the FA remains anterior to the anatomical axis (AA), defined as a line connecting the 1st and 5th metatarsal heads, with an average distance about 16% of the foot length across all walking speeds, and is also superior to the AA with an average distance about 2% of the foot length during normal and fast walking. Whereas, the FA shows a higher obliquity than the AA with an anteriorly more medial and superior orientation. This suggests that using the AA to represent the MP joint may result in overestimated MP joint moment and power and also underestimated muscle moment arms for MP extensor muscles. It was also found that walking speed has statistically significant effect on the position of the FA though the FA orientation remains unchanged with varying speed. The FA moves forwards and upwards towards a more anterior and more superior position with increased speed. This axis shift may help to increase the effective mechanical advantage (EMA) of MP extensor muscles, maximise the locomotor efficiency and also reduce the risk of injury. Those results may further our understanding of the contribution of the intrinsic foot structure to the propulsive function of the foot during locomotion at different speeds

KLF4-Mediated Plasticity of Myeloid-Derived Suppressor Cells (MDSCs)

Robustness of tissues refers to their capability to maintain normal functions despite perturbation such as injuries. Recent studies suggest a key role of the immune system in injury repair. In this process, several immune cell lineages exhibit considerable plasticity as they migrate toward the site of damage and contribute to repair. For example, myeloid-derived suppressor cells (MDSCs) are a heterogeneous group of immature cells and possess phenotypic plasticity in cancer, a pathological status that is considered as “wounds that do not heal.” They are characterized by their potent ability to suppress immune responses. In cutaneous wound healing, MDSCs not only execute their immunosuppressive function to inhibit inflammation but also stimulate cell proliferation once they adopt a fate of a totally different cell type. At a molecular level, we found that Krüppel-like factor 4 (KLF4), a transcription factor with multiple roles in homeostasis and disease development plays a critical role in regulating MDSCs. In this review, KLF4-mediated plasticity of MDSCs and the underlying mechanisms are discussed
