With a maximum tolerated dose of 100 mg/day and an acceptable toxicity profile, buparlisib may be effective in HNSCC, irrespective of PIK3CA mutational status. On-going clinical trials will help determine the developmental strategy of buparlisib while novel combinatory strategies including combination with immune checkpoint inhibitors should be considered. Importantly, biomarker strategies, including wider use of tumor sequencing and circulating tumor DNA, should be utilized to improve patient selection.Jatropha mutabilis (Pohl) Baill is an endemic species of the Caatinga biome, little studied in terms of chemical composition. The objective of this work was to develop an analytical methodology to quantify vitexin in the ethanolic extract of J. mutabilis and to evaluate the expectorant and antitussive activities in mice. The expectorant activity was performed by measuring the phenol red obtained from the bronchoalveolar fluid in animals and the antitussive activity was evaluated by the cough method induced by citric acid (0.4 M). The method developed by HPLC-DAD proved to be simple, linear, precise, accurate, robust and specific. Besides, both vitexin (0.2, 1 and 5 mg/kg) and the extract of J. mutabilis (20, 102, 510 mg/kg) showed efficacy in decrease cough and increase aqueous mucus in mice, but vitexin was more potent. Lastly, the identification of vitexin opens the possibility of new studies for J. mutabilis.The diagnosis of chronic obstructive pulmonary disease (COPD) mainly relies on spirometry. Due to the complexity of spirometry, easier-to-do impulse oscillometry (IOS) has been introduced as a complementary approach to conventional pulmonary function testing. Therefore, this study aimed to assess the efficacy of the diagnostic ability of IOS for diagnosing chronic obstructive pulmonary disease (COPD). This cross-sectional study was conducted at the Lung Health Center, Chiang Mai University, Thailand, between June 2019 and January 2020. IOS and spirometry were performed with all subjects suspected of having COPD. A Receiver Operating Characteristic (ROC) curve was plotted, the area under the ROC (AuROC) and 95%CI were compared among COPD and chronic smokers. One hundred and seventeen subjects suspected of having COPD with a mean age of 68.6 ± 8.6 years old were enrolled. Of these 103 (88.0%) were male. Thirty healthy subjects were also enrolled. IOS parameters including resistance at 5 Hz (R5), resonant frequency (Fres), area under reactance (AX), heterogeneity of resistance (R5-R20), and reactance at 5 Hz (X5) demonstrated excellent overall accuracy relative to the diagnosis of COPD with an AuROC ranging from 0.80 - 0.84. The AX ≥ 8.66 cmH2O/L represented an AuROC = 0.79, with a sensitivity of 79.1% and a specificity of 78.0% for the diagnosis of COPD. IOS is a valuable tool for use in the diagnosis of COPD. It may be used in subjects who cannot carry out the spirometric procedure.Parsley (Petroselinum crispum L.) has been used as food, spices and in folkloric medicine. Several scientific researches have been focalized on anti-inflammatory, anti-proliferative, antioxidant and other pharmacological activities of parsley. The aim of the present study was to evaluate the phytochemical composition, antioxidant and anticancer activity of P. crispum L aqueous and methanol extracts against Human glioblastoma cells U87MG. Adhesion assay was realized on different protein matrices (fibrinogen, fibronectin and poly-L-lysine) and the anti-proliferative effect was performed. Compared to aqueous extract, the methanol extract presented an important level of phenol contents. Five phenolic compounds were found using HPLC-DAD with quinic acid as the most abounded followed by gallic acid, acacetin, protocatechuic acid and Cirsilineol with 120753.07 ± 27450; 190 ± 25; 53.83 ± 10; 13.7 ± 2.5 and 2 ± 0.3 µg/mL respectively. The DPPH, ABTS+, OH radical, Iron (II) chelation and FRAP assays exhibited that methanol extract show a modulate antioxidant activity. The methanol extract shows the highest ability to inhibit cell adhesion to different protein matrices. In addition, it was found as a potential anti-proliferative. These results suggest for the first time that P. crispum methanol extract presents anti-adhesion and anti-proliferative proprieties.Bacillus cereus spores are concerns for food spoilage and foodborne disease in food industry due to their high resistance to heat and various disinfectants. The aim of this study was to investigate the inactivation of B. cereus spores by slightly acidic electrolyzed water (SAEW) in comparison to sodium hypochlorite (NaClO) with same available chlorine content (ACC). In this study, the efficacy of SAEW with different concentrations of ACC (40, 60, 80, 100, and 120 mg/L) on the inactivation of B. read more cereus spores, and the effect of SAEW combined with mild heat treatment (60°C), was examined in pure culture suspensions. Heat resistance and pyridine-2,6-dicarboxylic acid (DPA) release of the spores were also determined. The results showed that the sporicidal effect of the SAEW was significantly higher compared with the NaClO with the same concentration of ACC. Furthermore, the inactivation efficacy was largely dependent on ACC and treatment time. Moreover, the sporicidal activity of the SAEW was significantly improved when combined with a mild heat treatment (60°C). The majority of the DPA was released from spores, and the spores exhibited less resistance to heat after SAEW treatment for 30 min. These findings indicate that SAEW could effectively inactivate B. cereus spores, making it a promising and environmentally friendly decontamination technology for application in the food industry.2- or 4-Substituted 3-N-benzyltriazolylmethyl-13α-oestrone derivatives were synthesised via bromination of ring A and subsequent microwave-assisted, Pd-catalysed C(sp2)-P couplings. The antiproliferative activities of the newly synthesised brominated and phosphonated compounds against a panel of human cancer cell lines (A2780, MCF-7, MDA-MB 231) were investigated by means of MTT assays. The most potent compound, the 3-N-benzyltriazolylmethyl-4-bromo-13α-oestrone derivative exerted substantial selective cell growth-inhibitory activity against A2780 cell line with a submicromolar IC50 value. Computational calculations reveal strong interactions of the 4-bromo derivative with both colchicine and taxoid binding sites of tubulin. Disturbance of tubulin function has been confirmed by photometric polymerisation assay.Nutrient deficits have been repeatedly linked to cervical human papillomavirus (HPV) persistence, cervical neoplasia, and cervical cancer in case-control studies. This study sought to examine the relationship between overall diet quality and dietary components with the spontaneous resolution of cervical HPV over one year. A prospective observational cohort study was performed. Women with low-grade cervical cytology and/or positive HPV test completed a 24-hour dietary recall, from which the Healthy Eating Index (HEI)-2010, a score of overall diet quality, and scores in dietary categories were calculated. Participants were managed clinically according to national management guidelines. Those whose subsequent testing demonstrated normalization of cytology and/or HPV testing ("HPV resolution") were compared to those whose abnormalities persisted or progressed ("HPV non-resolution"). Twenty-six women were included in the HPV resolution group and 38 in the non-resolution group. They were observed for a median of 428 and 412 day, respectively (p = 0.09). There was no difference in overall diet quality between the groups. Intake of total and whole fruit, and seafood/plant protein were associated with HPV resolution in a logistic regression model (all p  less then  0.05). These findings could have important implications for the counseling and management of individuals with HPV infection of the cervix.Background Selective denervation of facial nerve branches ("Modified Selective Neurectomy") improves smile dynamics in patients with nonflaccid facial palsy, but functional morbidity such as oral incompetence has been reported. A comprehensive outcomes assessment of selective denervation will help clinicians educate patients regarding risks and benefits, and improve decision making as they incorporate this procedure into treatment algorithms. Methods Retrospective review identified selective denervation cases performed by the senior author between February 2019 and February 2020. Pre- and postoperative outcomes were assessed using chart review, the facial clinimetric evaluation (FaCE), the electronic clinician-graded facial function tool (eFACE), and an automated computer-aided facial assessment tool (Emotrics). Results Twenty consecutive selective denervation procedures were performed in 19 patients. Review of patient-reported outcome measures demonstrated mixed results. Favorably, patients reported smile improvement (13/17, 76.5%) and improvements in facial tightness/discomfort (8/17, 47.1%). Seven patients (41.2%) had worse drooling and five patients (29.4%) had increased difficulty chewing after surgery. Clinician-graded evaluation revealed statistically significant improvements in nasolabial fold depth at rest, oral commissure (OC) position at rest, and OC movement with smile. Total, static, and dynamic eFACE scores all demonstrated significant improvements. Computer-aided facial assessment revealed a significant increase in dental display, and an increase in OC excursion that trended toward significance. Conclusions Selective denervation improves patient-reported, clinician-graded, and automated smile metrics, but some patients experience exacerbations in oral incompetence and articulation difficulties, and must be counseled regarding these possibilities.Systematic phytochemical investigation of the bark and leaves of Betula alba was independently conducted. A new cyclic diarylheptanoid glucoside (1), five diarylheptanoids (2-6), a phenylethanoid (7), a methyl salicylate glycoside (8), a dihydrobenzofuran glucoside (9), an arylbutanoid glycoside (10), two lignan glycosides (11 and 12), a flavanone glucoside (13), and a triterpene (14) were isolated from the bark of B. alba. On the other hand, two cyclic diarylheptanoids (15 and 16), five flavonoids (17-21), a phenylpropanoid (22), a phenylbutanoid glucoside (23), and a monoterpene glucoside (24) were obtained from the leaves of B. alba. The structures of the isolated compounds (1-24) were identified on the basis of one- and two-dimensional NMR spectroscopic data. Compounds 1-24 were subsequently examined for aldose reductase (AR) inhibitory activity. Compounds 14 and 17-20 moderately inhibited AR activity with IC50 values ranging from 6.6 to 34 µM.
