Back.round/Purpose: Multipotent bone marrow-derived mesenchymal stromal cells (BMMSC) have been shown to possess the potential for tissue regeneration. The application of mesenchymal stromal cells (MSC)-derived growth factors and cytok.nes (GF/Ck.) has been implicated for the repair and regeneration of the damaged sk.n that occurs due to aging and exposure to environmental stress factors. Methods: We have used both qualitative and quantitative measurements of the GF/Ck. from the conditioned medium (CM) of a pooled population of BMMSC by antibody array analysis as well as by enzyme-link.d immunosorbent assay (ELISA). Furthermore, the CM was also used in a variety of in vitro biological assays to measure its protective properties in human sk.n fibroblasts. Results: We have characterized the secretome of BMMSC by analyzing the composition of the CM using a forty-one growth factor array system. Thirteen of these GF/Ck.extra cellular matrix (ECM)/ matrix metalloproteinases (MMP)-inhibitors in the CM were quantified owing to their involvement in sk.n repair cascade. In addition, we report that the BMMSC-CM was also able to protect dermal fibroblasts against tert-Butyl hydro peroxide (tbOH) induced oxidative stress and ultra violet B (UV-B) radiation induced cell damage. Conclusion: Based on the data presented here, we propose that BMMSC-derived CM may have the potential to promote health and rejuvenation of the aging sk.n.

Quantitative trait loci (QTL) analysis was conducted in bread wheat for 14 important traits utilizing data from four different mapping populations involving different approaches of QTL analysis. Analysis for grain protein content (GPC) sug- gested that the major part of genetic variation for this trait is due to environmental interactions. In contrast, pre-harvest sprouting tolerance (PHST) was controlled mainly by main effect QTL (M-QTL) with very little genetic variation due to environmental interactions; a major QTL for PHST was detected on chromosome arm 3AL. For grain weight, one QTL each was detected on chromosome arms 1AS, 2BS and 7AS. QTL for 4 growth related traits tak.n together detected by different methods ranged from 37 to 40; nine QTL that were detected by single-locus as well as two-locus analyses were all M-QTL. Similarly, single-locus and two-locus QTL analyses for seven yield and yield contributing traits in two populations respectively allowed detection of 25 and 50 QTL by composite interval mapping (CIM), 16 and 25 QTL by multiple-trait composite interval mapping (MCIM) and 38 and 37 QTL by two-locus analyses. These studies should prove useful in QTL cloning and wheat improvement through mark.r aided selection.

Blunt traumatic injuries to the superior gluteal artery are rare in clinic. A majority of injuries present as aneurysms following penetrating trauma, fracture pelvis or posterior dislocation of the hip joint. We reported a rare case of superior gluteal artery pseudoaneurysm following blunt trauma presenting as large expanding right gluteal hematoma without any bony injury. The gluteal hematoma was suspected clinically, confirmed by ultrasound and the arterial injury was diagnosed by CT angiography that revealed a large right gluteal hematoma with a focal contrast leak.ge forming a pseudoaneurysm within the hematoma. Pseudoaneurysm arose from the superior gluteal branch of right internal iliac artery, which was successfully angioembolized. The patient was discharged on day 4 of hospitalization with resolving gluteal hematoma. This report highlighted the importance of considering an arterial injury following blunt trauma to the buttock. with subsequent painful swelling. Ack.owledgment of this rare injury pattern was necessary to facilitate rapid diagnosis and appropriate treatment.

A mobile ad-hoc network.is an autonomous collection of mobile nodes that communicate over bandwidth constrained wireless link.. Due to nodal mobility, the network.topology may change rapidly and unpredictably over time. The routing protocols meant for wired network.cannot be used for mobile ad-hoc network.because of mobility of network. A number of routing protocols lik. Destination-Sequenced Distance-Vector (DSDV), Ad-Hoc On-Demand Distance Vector (AODV), Dynamic Source Routing (DSR), and Temporally Ordered Routing Algorithm have been implemented. The ad-hoc routing protocols can be divided into two classes;Table-Driven and On-Demand. This paper examines two routing protocols for mobile ad-hoc network.—the Destination Sequenced Distance Vector (DSDV), the table-driven protocol and the Ad-Hoc On- Demand Distance Vector routing (AODV), an on-demand protocol and propose an algorithm that facilitates efficient routing of the pack.t and failure recovery

Back.round and Aims: Androgenetic alopecia (AGA) is a common form of hair loss in both men and women. Despite its high prevalence and associated patient morbidity, the approved therapeutic options are limited to finasteride and minoxidil. The present study is aimed at assessing the efficacy of hair serum formulation, Trichosera®containing Bone marrow-derived mesenchymal stromal cells conditioned media as an active ingredient, for hair fall control and hair regrowth in healthy Indian human volunteers. Methods: The product was made using a 20% concentration of 10X Conditioned Media along with excipients. The final product was tested for physicochemical parameters, biomark.rs, total protein content and microbial limits as per our in-house specifications. Results: The primary irritation patch test showed that the product is non-irritant and dermatologically safe. A clinical study on 40 subjects was conducted to evaluate the effectiveness of the bioactive formulation in hair fall control and hair regrowth in healthy volunteers. Phototrichogram measurement showed hair density and hair growth rate increased significantly by 11.54% and 18.66% at week.24. Hair tensile strength also increased significantly by 41.10% at 12 week. follow-up. Hair pull test, to see a reduction in pulled hair and comb’s test to show a decrease in hair fall significantly improved from week.4 onwards. There were no significant adverse events in response to the product application. Conclusion: It is concluded that the hair serum product is completely safe on direct application to the scalp and showed significant improvement in the hair growth rate, hair density, scalp condition and reduction in hair fall. .

Introduction: The use of growth factors and cytok.nes in sk.n rejuvenation and reversal of photo ageing is a novel anti-ageing treatment. These factors provide a microenvironment that seems to favor tissue repair and regeneration. Methods: An open label, monocentric, single arm study to evaluate anti-ageing efficacy of conditioned medium obtained from adult human bone-marrow derived allogenic mesenchymal stromal cells (BMMSC) along with excipients formulated into a cosmetic serum, was conducted in 40 Indian female population aged 35 to 60 years, belonging to sk.n type IV - VI of Norwood Scale for a duration of 90 days. Parameters—fine lines, wrink.es, crow’s feet, evenness of sk.n tone, sk.n firmness/laxity, hydration of sk.n, homogeneity of age spots, and visible pores were used to evaluate the anti-ageing and rejuvenating properties of the test product. Results and Discussion: Improvement was seen in majority of parameters starting from 15 - 30 days. Product was safe and well tolerated as per the dermatologist and subjects’ self-assessment.
