AIM To evaluate physical fitness and cardiovascular effects in rats with renovascular hypertension, two kidneys, one clip (2K1C) submitted to voluntary exercise (ExV). MAIN METHODS 24 h after surgery (SHAM and 2K1C) rats were submitted to ExV for one week (adaptation). ExV adherent rats were separated into exercise (2K1C-EX and SHAM-EX) or sedentary (2K1C-SED and SHAM-SED) groups. After 4 weeks, exhaustion test, plasma lactate, cardiovascular parameters were evaluated and gastrocnemius muscle was removed for evaluation of gene expression of muscle metabolism markers (PGC1α; AMPK, SIRT-1, UCP-3; MCP-1; LDH) and of the redox process. KEY FINDINGS ExV decreased blood lactate concentration and increased SOD and CAT activity and a SIRT-1 and UCP-3 gene expression in the gastrocnemius muscle of 2K1C-ExV rats compared to 2K1C-SED rats. Gene expressions of PGC1α, UCP-3, MCT-1, AMPK were higher in 2K1C-ExV rats compared to SHAM-SED rats. Blood pressure in 2K1C-ExV was lower compared to 2K1C-SED and higher in SHAM-SED rats. Reflex bradycardia in 2K1C-EX rats increased compared to 2K1C-SED and was similar to SHAM-SED. The variation in mean blood pressure induced by ganglion blocker hexamethonium and Ang II AT1 receptor antagonist, losartan in the 2K1C-ExV rats was smaller compared to the 2K1C-SED rats and it was similar to the SHAM-SED rats. SIGNIFICANCE O ExV induced adaptive responses in 2K1C-ExV rats by decreasing sympathetic and Ang II activities and stimulating intracellular signaling that favors redox balance and reduced blood lactate concentration. These adaptive responses, then, contribute to reduced arterial pressure, improved baroreflex sensitivity and physical fitness of 2K1C rats. Paeonol is a bioactive phenol present in Dioscorea japonica, Paeonia suffruticosa and Paeonia lactiflora. It is reported for various pharmacological activities. AIM To review chemistry, pharmacokinetics, pharmacological activities as well as various formulations of paeonol. MATERIALS AND METHODS A literature search was done using different search terms for paeonol by using different scientific databases like PubMed, Scopus and ProQuest. Scientific papers published during the period 1969 to 2019 were comprehensively reviewed. Fadraciclib concentration KEY FINDINGS Researchers have synthesized methoxy, ethoxy, piperazine, chromonylthiazolidine, phenol-phenylsulfonyl, alkyl ether, aminothiazole, tryptamine hybrids and paeononlsilatie derivatives to enhance the stability of paeonol. These derivatives were synthesized and evaluated for in vitro series of biological activities like anti-inflammatory, tyrosinase inhibitory, neuroprotective, anticancer and antiviral activity. Regardless of valuable therapeutic potential, the clinical use of paeonol is restricted due to poor water solubility, low oral bioavailability, low stability and high volatility at room temperature. To enhance the bioavailability of paeonol various formulations are prepared and evaluated for its activity. Paeonol formulations can be categorized as conventional-tablets, topical gel and hydrogel; polymeric delivery system-microparticles, microsponges, dendrimers, nanocapsules, polymeric nanoparticles, nanospheres; lipid-based delivery systems-microemulsion, self-micro-emulsifying drug delivery, liposome, transethosomes, ethosomes, niosomes, proniosomes, lipid-based nanoparticles and nanoemulsion of paeonol. SIGNIFICANCE Paeonol has a potential to be developed as a techno-commercial product with respect to its multi-faceted pharmacological properties. Even though in vitro and in vivo studies have been reported the important activities of paeonol, its commercial utilization requires extensive safety and efficacy data. Breast cancer is the frequently diagnosed cancer among women and it is the most lethal malignancy in women globally. With one million cases every year, breast cancer is the fast-growing cancer type that has a high prevalence rate in young women. The limitations and undesirable side effects of conventional therapies like chemotherapy and radiotherapy on malignant tumors necessitate the development of alternative therapeutic approaches. Gene therapy has emerged as a promising approach to cure a variety of malignant cancer types which involves the delivery of functional gene directly into the target tumor tissue. Efficient gene therapy approach relies on the effective delivery of therapeutic genes to the desired cell type. In this regard, biological and non-biological gene delivery vectors are used to protect the naked foreign DNA to mediate effective tissue entry of the desired gene of interest. In this review, the use of bacterial and viral vectors for breast cancer gene therapy was summarized. BACKGROUND Brain abscess is an uncommon condition, but carries high mortality. Current treatment guidelines are based on limited data. Surveillance of clinical, radiological and microbiology data is important to inform patient stratification, interventions, and antimicrobial stewardship. METHODS We undertook a retrospective, observational study of patients with brain abscess, based on hospital coding, in a UK tertiary referral teaching hospital. We reviewed imaging data, laboratory microbiology, and antibiotic prescriptions. RESULTS Over a 47 month period, we identified 47 adults with bacterial brain abscess (77% male, median age 47 years). Most of the abscesses were solitary frontal or parietal lesions. A microbiological diagnosis was secured in 39/47 (83%) of cases, among which the majority were of the Streptococcus milleri group (27/39; 69%), with a predominance of Streptococcus intermedius (19/27; 70%). Patients received a median of 6 weeks of intravenous antibiotics (most commonly ceftriaxone), followed by variable oral follow-on regimens. Ten patients (21%) died, up to 146 days after diagnosis. Mortality was significantly associated with increasing age, multiple abscesses, immunosuppression and the presence of an underlying cardiac anomaly. CONCLUSION Our data suggest that there has been a shift away from staphylococcal brain abscesses, towards S. intermedius as a dominant pathogen. In our setting, empiric current first line therapy with ceftriaxone remains appropriate on microbiological grounds and narrower spectrum therapy may sometimes be justified. Mortality of this condition remains high among patients with comorbidity. Prospective studies are required to inform optimum dose, route and duration of antimicrobial therapy. BACKGROUND A longitudinal vaginal septum is a rare congenital anomaly that can cause dyspareunia, difficulty with tampon insertion, persistent vaginal bleeding and dysmenorrhea. Various surgical techniques have been described. CASE We present a 14 year old female with obesity and diabetes mellitus with uterine didelphys and double vagina with a longitudinal vaginal septum. The patient presented with dysmenorrhea. Resection of the longitudinal vaginal septum utilizing a GIA and EndoGIA (Medtronic, Inc, Doral Fl) stapler device was performed. SUMMARYAND CONCLUSIONS We introduce a safe and effective technique for resecting a longitudinal vaginal septum utilizing stapler technology. This technique eliminates the potential risk of thermal injury to nearby structures from currently described methods. Bulgaria is one of European countries where trichinellosis continues to be regularly diagnosed and registered. The clinical and epidemiological features of 72 cases of trichinellosis associated with five outbreaks caused by Trichinella spiralis and Trichinella britovi between 2009 and 2011, are described. At hospital admission, patients were often initially treated with antibiotics, without any improvement. A range of signs and symptoms were recorded, including myalgia, elevated temperature, arthralgia, difficulty with movement, facial oedema, conjunctival hyperaemia, ocular haemorrhages, diarrhoea, skin rash, headache, and fatigue. Due to the variable clinical course of the disease, the diagnostic process for trichinellosis is often complex and difficult. This means the diagnosis may be established late for an appropriate treatment, potentially leading to a severe course of the disease with complications. Laboratory abnormalities were expressed by marked eosinophilia (97.2%), leucocytosis (70.8%), elevated serum creatine phosphokinase levels (82%), and antibody-positive results by ELISA and indirect hemagglutination. Patients were treated with albendazole (Zentel) 10 mg/kg for 7-10 days. In two outbreaks, the aetiological agent was T. spiralis, in one outbreak T. britovi, and an unknown Trichinella species in the fourth outbreak. The sources of infection were domestic pigs, probably fed with scraps and offal of wild game. In one outbreak, T. spiralis was also detected in brown rats trapped close to where the pig had been raised in the backyard. These epidemiological factors are relevant in considering implementation of targeted control programmes. OBJECTIVE Quantify the impact of a psycho-education-based cognitive rehabilitation intervention on breast cancer survivors' self-report of cognitive function, and investigate the feasibility of accrual, adherence, and multi-site program delivery using secure telehealth conferencing. DESIGN Prospective, non-blinded, wait-list controlled pilot study. SETTING Non-profit academic medical center and university medical center with associated community practice affiliates. PARTICIPANTS Adult female survivors of stage I-III breast cancer reporting cognitive complaints 2-months-5-years after chemotherapy. Ongoing endocrine and/or anti-HER-2 therapy was allowed. EXCLUSIONS history of other conditions involving impaired cognitive function. Combination referred and volunteered sample. 107 women screened, 61 consented, 52 analyzed. No attrition due to adverse events. Group allocation based on consent timing and next scheduled cohort to minimize wait-time for wait-list controls. INTERVENTION Psycho-education-based cognitiv of psycho-education-based cognitive rehabilitation as an intervention for decreased PCF in breast cancer survivors with cognitive complaints following chemotherapy. Feasibility for accrual, adherence, and participant satisfaction with secure telehealth conferencing was demonstrated. These positive pilot study results will inform future work. We previously revealed the crucial roles of a chemokine, CX3CL1, and its receptor, CX3CR1, in skin wound healing. Although repeated wounds frequently develop into skin cancer, the roles of CX3CL1 in skin carcinogenesis remain elusive. Here, we proved that CX3CL1 protein expression and CX3CR1+ macrophages were observed in human skin cancer tissues. Similarly, we observed the enhancement of CX3CL1 expression and the abundant accumulation of CX3CR1+ tumor-associated macrophages (TAMs) with M2-like phenotypes in the skin carcinogenesis process induced by the combined treatment with 7,12-dimethylbenz-(a)anthracene (DMBA) and 12-O-tetradecanoylphorbol-13-acetate (TPA). In this mouse skin carcinogenesis process, CX3CR1+ TAMs exhibited M2-like phenotypes with the expression of Wnt3a and angiogenic molecules including vascular endothelial growth factor (VEGF) and matrix metalloproteinase (MMP)-9. Compared to wild-type mice, CX3CR1-deficient mice showed fewer numbers of skin tumors with a lower incidence. Concomitantly, M2-macrophage numbers and neovascularization were reduced with the depressed expression of angiogenic factors and Wnt3a.
