ICTCs provide a critical entry point for prevention, care and support for both people affected by HIV/AIDS and general population. The study was conducted with the objective of evaluating ICTCs in terms of infrastructure and staffing, services provided, level of utilization and quality of counselling. The structure and process evaluation of 13 ICTCs under National AIDS control programme III (NACP III) was carried out in a Coastal District of South India. The evaluation was carried out using UNAIDS Tools between July and September of 2010. Twelve out of 13 ICTCs (92%) had adequate infrastructure and staff. Most of the general clients (75%) attending ICTCs were provider initiated and 84.5% of antenatal women in the district attended pre-test counselling and also underwent HIV testing. Twenty six pre-test counselling sessions and 12 post test sero-positive counselling sessions were observed. Pre-test counselling content assessment revealed that only 57.4% of sessions address all the issues whereas, 79% of post-test sessions addressed most of the issues during counselling. Counsellors’ skills assessment information gathering and information giving were found to be poorly done. It was found that post test counselling sessions were not conducted for clients with HIV negative report. The aspects of ICTCs such as services provided at the centers, utilization of services by the clients, infrastructure and staffing pattern were found to be adequate. Counselling forms the vital component of the ICTC needed improvement and post test counselling should be mandatory to all the clients.

OBJECTIVES: Dengue is a mosquito-borne viral disease globally transmitted by Aedes aegypti. The most effective method to prevent the transmission of the disease is proficient vector control. Understanding the breeding behaviour of the responsible vectors is very pertinent in this regard; therefore, the present study was conducted to understand Ae. aegypti behaviour regarding the selection of containers for oviposition in the megacity of Delhi. METHODS: A household survey in different localities within Delhi was carried out during 2018-2019. All available containers were inspected for the presence of immature Ae. aegypti. In entomological surveillance, the ovipositional preference of Aedes was computed using the breeding preference ratio, container index in the field, and laboratory settings, and associations of dengue cases with monthly variation in environmental factors and container type were also calculated. RESULTS: The household larval survey in 40 localities showed that 40% of 27,776 water-holding containers in 3,400 houses were plastic, followed by overhead tanks (26.2%), and coolers (12.1%). The most preferred breeding habitat was clay pots (9.3%), followed by metallic containers (8.5%) and solid waste (7.1%). A laboratory-based study showed that Aedes preferred clay containers (81.8%) over 4 other types of containers (plastic, paper, metal, and glass). CONCLUSIONS The present study provides a rationale for using clay containers as a possible surveillance tool (ovitraps) or as a vector control tool. This information might aid researchers in developing novel traps and targeting preferred containers for larval control activities during transmission and non-transmission seasons.

Isoliquiritigenin (ISL), a phenolic compound derived from licorice, exhibits various biological activities, including anti-inflammatory, anti-viral, anti-tumor, and antioxidant effects. However, the molecular mechanisms underlying its anti-cancer effects are not well understood in SK-MEL-28 melanoma cells. Melanoma, a highly aggressive and treatment-resistant cancer, remains a significant health challenge. This study investigates the anti-cancer effects of ISL, focusing on identifying reactive oxygen species (ROS)-mediated apoptosis mechanisms on SK-MEL-28 melanoma cells. Our results show that ISL treatment induces apoptosis in SK-MEL-28 cells, as evidenced by the cleavage of caspase-9, -7, -3, and PARP. ISL increased Bax expression, decreased Bcl-2 expression, and promoted cytochrome C release into the cytosol. ISL also reduced the expression of cell cycle markers, including cyclin D1, D3, and survivin. Notably, ISL treatment markedly increased intracellular ROS levels and pretreatment with N-acetyl cysteine, a ROS scavenger, abrogated the ISL-induced inhibition of the p38/mTOR/STAT3 pathway and prevented apoptosis.Moreover, ISL significantly diminished the constitutive phosphorylation of mTOR and STAT3 in SK-MEL-28 cells by blocking the phosphorylation of p38 MAPK, an upstream kinase of mTOR. Pharmacological inhibition of mTOR attenuated the STAT3 signaling, indicating that mTOR acts as an upstream kinase of STAT3 in these cells. Collectively, these findings demonstrate that ISL inhibits SK-MEL-28 cell growth by downregulating cell survival proteins and inducing apoptosis through ROS generation.

Bacillus Calmette-Guérin (BCG) is an attenuated strain of Mycobacterium bovis. Although it was developed as a prophylactic vaccine against tuberculosis (TB), researchers have also evaluated it for preventing cancer development or progression. These studies were inspired by the available data regarding the protective effects of microbial infection against cancers and an inverse relationship between TB and cancer mortality. Initial studies demonstrated the efficacy of BCG in preventing leukemia, melanoma and a few other cancers. However, mixed results were observed in later studies. Importantly, these studies have led to the successful use of BCG in the tertiary prevention of non-muscle invasive bladder cancer, wherein BCG therapy has been found to be more effective than chemotherapy. Moreover, in a recently published 60-year follow-up study, childhood BCG vaccination has been found to significantly prevent lung cancer development. In the present manuscript, we reviewed the studies evaluating the efficacy of BCG in cancer prevention and discussed its putative mechanisms. Also, we sought to explain the mixed results of BCG efficacy in preventing different cancers.

Purpose::Fingertip injuries are common in industrial production activities as well as in domestic work. Loss of pulp hampers daily life activities. Functional and aesthetic aspects are important in fingertip reconstruction. The bone is usually exposed along with soft tissue loss. Therefore to reconstruct the pulp flap with adequate bulk is required.Methods::We reported a case series of 12 patients with the injury over the volar aspect of distal phalanx of the index or middle finger. In all cases, laterally based thenar flap was chosen. The flap donor site was closed primarily in most of cases, while 4 patients required skin graft. The flap was detached between 2-3 weeks. Functional assessment was done using static and dynamic 2-point discrimination and range of motion at each joint. The aesthetic outcome was assessed through questionnaire. The results were analyzed using the unpaired t-test (SPSS version 21). Results::Partial necrosis occurred in 2 cases while rest of flaps survived successfully. Static 2-point discrimination ranged from 6-10 mm, mean 8.6 mm; and dynamic 2-point discrimination ranged from 8-10 mm, mean 8.9 mm. The mean satisfaction score was (4.0 ± 0.55).Conclusion::Thenar flap is a good choice for reconstruction of the finger pulp as it provides the bulk with good functional and aesthetic outcome.

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) suggested 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 taken 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 marker aided selection.

BACKGROUND/AIMS: Capsaicin (8-methyl-N-vanillyl-6-ninenamide), a compound found in hot peppers, has been reported to have different physiological actions on different cell types. Not much work has been done about the effect of capsaicin on the function of interstitial cells of Cajal (ICC). In the present study, we examined the action of external application of capsaicin on pacemaker activity in the cultured ICC from the small intestine of mouse. METHODS: We investigated the effect of capsaicin on pacemaker currents in cultured ICC from the small intestine of mouse using a whole cell patch-clamp technique and Ca2+-imaging analysis. RESULTS: When capsaicin was applied externally to the pacemaker generating ICC, it completely inhibited the pacemaker potential under current-clamp mode (I = 0) and the pacemaker current under voltage-clamp mode at a -70 mV of holding potentials. The effect of capsaicin on pacemaker activity in ICC was shown dose dependently. The effect of capsaicin was not through the transient receptor potential of the vanilloid type 1 (TRPV1) channel as capsazepine did not block the effect of capsaicin. L-NAME, an inhibitor of nitric oxide synthase, also did not block the capsaicin-induced effects. When the action of capsaicin was examined in the intracellular calcium oscillation, it completely abolished the calcium oscillation. CONCLUSIONS: These results prove that the capsaicin has the inhibitory effects on the ICC which is carried out neither through TRPV channel nor the nitric oxide production. Intracellular Ca2+ was also an important target for actions of capsaicin on ICC.

STUDY DESIGN: Case series. PURPOSE: To describe paraspinal transposition flap for coverage of sacral soft tissue defects. OVERVIEW OF LITERATURE: Soft tissue defects in the sacral region pose a major challenge to the reconstructive surgeon. Goals of sacral wound reconstruction are to provide a durable skin and soft tissue cover adequate for even large sacral defects; minimize recurrence; and minimize donor site morbidity. Various musculocutaneous and fasciocutanous flaps have been described in the literature. METHODS: The flap was applied in 53 patients with sacral soft tissue defects of diverse etiology. Defects ranged in size from small (6 cmx5 cm) to extensive (21 cmx10 cm). The median age of the patients was 58 years (range, 16-78 years). RESULTS: There was no flap necrosis. Primary closure of donor sites was possible in all the cases. The median follow up of the patients was 33 months (range, 4-84 months). The aesthetic outcomes were acceptable. There has been no recurrence of pressure sores. CONCLUSIONS: The authors conclude that paraspinal transposition flap is suitable for reconstruction of large sacral soft tissue defects with minimum morbidity and excellent long term results.
