There were no significant differences between the groups in other postoperative complications (one of 25 versus 0 of 25), rate of recurrent hernia within 1 year (none in either group) or postoperative pain. Conclusion Conventional fascial closure and peritoneal bridging did not differ with regard to seroma formation after laparoscopic ventral hernia repair. Trial registration ClinicalTrials.gov (NCT03344575).The sulfone functional group has a strong capacity to direct the asymmetric transfer hydrogenation (ATH) of ketones by [(arene)Ru(TsDPEN)H] complexes by adopting a position distal to the η 6 -arene ring. This preference provides a means for the prediction of the sense of asymmetric reduction. The sulfone group also facilitates the formation of a range of reduction substrates and its ready removal provides a route to enantiomerically-enriched alcohols which would otherwise be extremely difficult to prepare by direct ATH of the corresponding ketones.As an outcome of chronic liver disease, liver fibrosis involves the activation of hepatic stellate cells (HSCs) caused by a variety of chronic liver injuries. It is important to explore approaches to inhibit the activation and proliferation of HSCs for the treatment of liver fibrosis. PLK1 is overexpressed in many human tumour cells and has become a popular drug target in tumour therapy. Therefore, further study of the function of PLK1 in the cell cycle is valid. In the present study, we found that PLK1 expression was elevated in primary HSCs isolated from CCl4 -induced liver fibrosis mice and LX-2 cells stimulated with TGF-β1. Knockdown of PLK1 inhibited α-SMA and Col1α1 expression and reduced the activation of HSCs in CCl4 -induced liver fibrosis mice and LX-2 cells stimulated with TGF-β1. We further showed that inhibiting the expression of PLK1 reduced the proliferation of HSCs and promoted HSCs apoptosis in vivo and in vitro. Furthermore, we found that the Wnt/β-catenin signalling pathway may be essential for PLK1-mediated HSCs activation. Together, blocking PLK1 effectively suppressed liver fibrosis by inhibiting HSC activation, which may provide a new treatment strategy for liver fibrosis.Optimized conditions are needed to refold recombinant proteins from bacterial inclusion bodies into their biologically active conformations. In this study, we found two crucial requirements for efficient refolding of cationic tetrameric chicken avidin. The first step is to eliminate nucleic acid contaminants from the bacterial inclusion body. The electrostatic interactions between the remaining nucleic acids and proteins strongly enhanced protein aggregation during the refolding process. The cysteine specific reversible S-cationization procedure was successfully employed for large-scale preparation of nucleic acid free denatured protein without purification tag system. The second step is the intramolecular disulfide formation prior to refolding in dialysis removing denaturant. Disulfide intact monomeric avidin showed efficient formation of biologically active tetrameric conformation during the refolding process. Using this optimized refolding procedure, highly cationic avidin derivative designed as an intracellular delivery carrier of biotinylated protein was successfully prepared.Objective Previous studies have presented controversial results between Western diet and the risk of inflammatory bowel disease (IBD). This study aimed to evaluate the role of a pre-illness Western dietary pattern in the development of IBD. Methods Western dietary pattern was defined as a dietary pattern that met two of the following characteristics, either with increased intake of refined grains, red and processed meat, animal protein, animal fats, high-fat dairy products, or with low consumption of fruit and vegetables. Four medical databases (PubMed, Embase, the Cochrane Library and the China National Knowledge Infrastructure) were searched to identify all relevant references. Risk estimates and corresponding 95% confidence intervals (CIs) were pooled using a random-effects model. Results Nine studies (seven case-control studies and two prospective cohorts) were included, with a total of 1491 IBD cases and 53 270 controls. A Western dietary pattern was associated with a risk of all IBD (relative risk [RR] 1.92, 95% CI 1.37-2.68) and separately with CD (RR 1.72, 95% CI 1.01-2.93) and UC (RR 2.15, 95% CI 1.38-3.34). Subgroup analysis by region showed that Western dietary pattern was associated with the risk of CD and UC for studies performed in Europe (RR 2.25, 95% CI 1.44-3.50 for CD; RR 2.65, 95% CI 1.61-4.36 for UC). The pooled RR was 2.26 (95% CI 1.42-3.59) in the pediatric CD subgroup. Conclusion This meta-analysis indicates that a Western dietary pattern might increase the risk of CD and UC.

Mutations in LPAR6 and keratin 71 (KRT71), result in unusual fur growth and hair structure in several cat breeds (Cornish Rex, Devon Rex and Selkirk Rex). Here, we performed target sequencing of the LIPH, LPAR6 and KRT71 genes in six cat breeds with specific hair-growth phenotypes. A LIPH genetic variant (LIPHc.478_483del; LIPHp.Ser160_Gly161del) was found in Ural Rex cats with curly coats from Russia, but was absent in all other cat breeds tested. In silico three-dimensional analysis of the LIPH mutant protein revealed a contraction of the α3-helix structure in the enzyme phospholipid binding site that may affect its activity.Epsilon toxin (ETX) is a 33-kDa pore-forming toxin produced by type B and D strains of Clostridium perfringens. We previously found that ETX caused haemolysis of human red blood cells, but not of erythrocytes from other species. The cellular and molecular mechanisms of ETX-mediated haemolysis are not well understood. Here, we investigated the effects of ETX on erythrocyte volume and the role of the putative myelin and lymphocyte (MAL) receptors in ETX-mediated haemolysis. We observed that ETX initially decreased erythrocyte size, followed by a gradual increase in volume until lysis. Moreover, ETX triggered phosphatidylserine (PS) exposure and enhanced ceramide abundance in erythrocytes. Cell shrinkage, PS exposure and enhanced ceramide abundance were preceded by increases in intracellular Ca2+ concentration. Interestingly, lentivirus-mediated RNA interference studies in the human erythroleukaemia cell line (HEL) cells confirmed that MAL contributes to ETX-induced cytotoxicity. Additionally, ETX was shown to bind to MAL in vitro. The results of this study recommend that ETX-mediated haemolysis is associated with MAL receptor activation in human erythrocytes. These data imply that interventions affecting local MAL-mediated autocrine and paracrine signalling may prevent ETX-mediated erythrocyte damage.Purpose We explored changes in health services utilization associated with the Biosimilars Initiative introduced in British Columbia on May 27, 2019. To maintain drug coverage, the policy requires users of originator infliximab or etanercept to transition to biosimilar versions. We present a three-month interim analysis of this initiative. Methods We conducted a rapid monitoring analysis to evaluate changes in health services utilization three months after the policy was introduced compared with a three-year period before the policy's introduction. Using the administrative claims data of the British Columbia Ministry of Health, we assembled three historical cohorts and one policy cohort of users of each originator drug (8 cohorts in total). Cumulative incidences of medication refills, switching, and visits to physicians were the outcome measures used to compare policy and historical cohorts. Likelihood ratios were used to quantify statistical differences between each policy cohort and its respective historical controls. Likelihood ratios above 7.1 were considered statistically significant. Results The four infliximab cohorts included 436 patients on average, mean age 56 to 59, 53% to 55% females. The four etanercept cohorts included 1826 patients on average, mean age 57 to 58, 60% to 63% females. Three months after the policy's introduction, 21% of patients treated in the policy cohorts transitioned to the biosimilar versions. Health services utilization in the policy cohorts were consistent with the historical cohorts. Conclusions An increase in visits to physicians was expected but not detected in the first three months of the Biosimilars Initiative. The impacts of the policy will continue to be monitored.Cell-penetrating peptides (CPPs) have gained much attention as carriers of hydrophilic molecules, such as drugs, peptides, and nucleic acids, into cells. CPPs are mainly composed of cationic amino acid residues, which play an important role in their intracellular uptake via interactions with acidic groups on cell surfaces. In addition, the secondary structures of CPPs also affect their cell-membrane permeability. Based on this knowledge, a variety of cell-penetrating foldamers (oligomers that form organized secondary structures) have been developed to date. In this account, we describe recent attempts to develop cell-penetrating foldamers containing various building blocks, and their application as DDS carriers.Aim Feeding problems have been described in young children with oesophageal atresia (OA). The primary aim of this study was to determine the specific concerns of parents and carers of infants and young children with OA regarding introducing solids and moving up to family foods. Methods A questionnaire was developed for parents and carers of infants and children with OA, aged 12 months to 6 years. Questionnaires were completed by 20 parents attending a multidisciplinary OA clinic between June 2016 and June 2017. Demographics and parental concern regarding feeding milestones were collected. The Montreal Children's Hospital Feeding Scale was completed. Results The majority of children (95%) had type C OA. Eleven (55%) parents agreed/strongly agreed that they were concerned about their child's feeding prior to the introduction of solids and about moving to more textured solids. The most common concern was choking and food impaction for both time points. Twelve (60%) parents agreed/strongly agreed that the majority of mealtimes in their child's first 1-2 years of life were stressful. Thirteen (65%) parents reported avoiding particular foods due to their child's OA. The majority of children (n = 17) had no feeding difficulty according to an objective scale, and the rest had minor difficulty. Conclusions Parental concern around feeding still exists in infants and children without a severe feeding difficulty. Multidisciplinary involvement, including a dietitian and speech pathologist, from an early age is important for infants and children with OA.Background We assessed the antitumor activity of cabozantinib, a potent multireceptor oral tyrosine kinase inhibitor, in patients with hormone receptor-positive breast cancer with bone metastases. Patients and methods In this single-arm multicenter phase II study, patients received an initial starting dose of 100 mg, later reduced to 60 mg, per day. The primary endpoint was the bone scan response rate. Secondary endpoints included objective response rate by RECIST, progression-free survival (PFS), and overall survival (OS). Results Of 52 women enrolled, 20 (38%) experienced a partial response on bone scan and 6 (12%) had stable disease. Prior to the first repeat bone scan at 12 weeks, 19 (35%) patients discontinued study treatment because of early clinical progression or unacceptable toxicity. RECIST evaluation based on best overall response by computed tomography revealed stable disease in extraosseous tissues in 26 patients (50%) but no complete or partial responses. In 25 patients with disease control on bone scan at 12 weeks, only 3 (12%) patients developed extraosseous progression.
