An in vitro biological model for evaluation of the anti-dandruff performance of hair care products was established. In this model, Malasseziafurfur(***) was used as indicator bacteria with pigskin as *** model functions in following steps: pretreatment for the substrate; inoculation of indicator bacteria;measuring the bacteriostatic efficacy by the contact plates after washing the pigskin with the sample shampoo;calculation of the effective index P; evaluation of the anti-dandruff performance by the effective index P. Three kinds of anti-dandruff agents including BPT, ZPT and OCT were tested by the model. Results showed that the order for antibacterial efficacy of the anti-dandruff agents within the mass fraction range of 0.1 %~2.0% was BPT>ZPT>OCT. Results of the evaluation on each type of shampoo showed that: one displays no antidandruff efficacy; three displays medium anti-dandruff efficacy; two displays strong anti-dandruff efficacy.

Introduction: Apart from smoking as the known risk factor for lung cancer, recent developments implicate occupational exposure to carcinogens, indoor air pollution and dietary factors as other causative agents. In our study, we have analyzed the clinical and pathological profile of lung cancer patients treated at our center over a period of 8 years. Aim: To find the demographic and clinicopathological profile of lung cancer patients admitted to the oncology unit. Methods: This retrospective record based analysis includes a cohort of 1248 patients diagnosed with lung cancer, at a tertiary cancer care center in Bangalore, South India. This study includes data of patients admitted during the period 2010 to 2018, retrieved from the Hospital’s emergency medical records (EMR). Their demographic profile, clinical correlates, radiological profile and diagnostic details were studied. Benign tumours, malignant pleural disease and sarcomatoid tumors were excluded from this study. Results: Adenocarcinoma (AC) was detected among 70.4% of patients, Squamous cell carcinoma (SCC) among 15.3% and Small cell lung cancer (SCLC) among 14.3% of lung cancer admissions. Male to female ratio was 2.95:1. It was found that the median age of lung cancer patients was 61 years. >60% of lung cancer patients were from the 51 - 70 year age-group. Across the three types of cancers among the patients in Stage 3B to 4 strata, >35% received palliative chemotherapy and >20% received palliative chemotherapy + radiation. Conclusion: In our study, AC is the most common histological subtype (>70%) of lung cancer. The outcome of lung cancer patients can be considerably impacted by addressing risk factors through preventive measures implemented in the community.

The mechanical mismatch effect frequently occurs in the dissimilar materials welded joints, thus leading to plastic gradient at the interface between the weld and heat-affected zone(HAZ). In this work, the boron steel and Q235 steel were selected for laser tailor welding,which obtained boron/Q235 steel tailor-welded blanks(TWBs). The method of welding with synchronous thermal field(WSTF) was utilized to eliminate the mismatch effects in TWBs. The WSTF was employed to adjust cooling rates of welded joints, thereby intervening in the solidification behaviors and phase transition of the molten pool. Boron/Q235 steel was welded by laser under conventional and WSTF(300-600 ℃) conditions, respectively. The results show that the microstructure of weld and HAZ(boron) was adequately transitioned to ferrites and pearlites instead of abundant martensite by WSTF. Meanwhile, the discrepancy of microhardness and yield strength between various regions of welded joints was greatly reduced, and the overall plasticity of welded joints was enhanced by WSTF. It is indicated that WSTF can effectively contribute to reducing plastic gradient and achieving mechanical congruity in welded joints by restraining the generation of hardbrittle phase, which could significantly improve the formability of TWBs in subsequent hot stamping.
