In this paper, two most representative hernia repair meshes were prepared with 0.15 mm polypropylene monofilaments via warp knitting technology, and their mechanical properties were tested in various aspects. Meanwhile, a focused investigation of the boundary conditions between the sutures and the mesh was simulated in several directions innovatively. The results revealed that the hernia repair mesh with different structures has different mechanical properties, and the mechanical properties of standard hernia repair mesh were superior to that of lightweight hernia repair mesh. In order to reduce foreign body sensation and postoperative adverse reactions significantly, the lightweight hernia repair mesh may be preferred. At the same time, the mesh should be placed in the proper direction to comply with the anisotropy of abdominal wall during operation. The area where the hernia mesh is in contact with the sutures was vulnerable to damage. The curved or wrinkled area of the hernia repair mesh increases with the increase of load, which may lead to poor tissue growth, a strong inflammatory response, and even the recurrence of the hernia. Therefore, the hernia repair meshes with different structures may require unique suture techniques. And they also should be further treated prior to implantation. This study provides a theoretical basis for development, utilization and improvement of meshes. Further research will focus on the biomechanical properties of the mesh after implantation in vivo studies.Coating and cross-linking have been widely used to improve the properties of materials in tissue engineering. A chitosan/hydroxyapatite (CS/HA) comby scaffold with high porosity was prepared via a 3D printed pore-forming mold. The scaffold was then treated with gelatin (Gel) coating and was cross-linked by glutaraldehyde (GA) in order to improve the mechanical strength. The materials were characterized by infrared spectroscopy (IR) and X-ray diffraction (XRD). The structure of the scaffolds was observed by Scanning Electron Microscopy (SEM). Compression tests were carried out to evaluate the strength of the scaffolds. The behaviors and responses of preosteoblast cells on the scaffolds were studied as well. The results showed that gelatin coating and cross-linking significantly enhanced the mechanical strength of the porous scaffolds. Cell culture experiment indicated that the scaffold had good cytocompatibility. The combined application of 3DP structure construction and biopolymer coating/cross-linking would offer some new ideas in fabrication of porous scaffolds with enhanced strength and good biocompatibility for tissue engineering.The application of biodegradable materials to stent design has the potential to transform coronary artery disease treatment. It is critical that biodegradable stents have sustained strength during degradation and vessel healing to prevent re-occlusion. Proper assessment of the impact of corrosion on the mechanical behaviour of potential biomaterials is important. Investigations within literature frequently implement simplified testing conditions to understand this behaviour and fail to consider size effects associated with strut thickness, or the increase in corrosion due to blood flow, both of which can impact material properties. A protocol was developed that utilizes micro-scale specimens, in conjunction with dynamic degradation, to assess the effect of corrosion on the mechanical properties of a novel Fe-316L material. Dynamic degradation led to increased specimen corrosion, resulting in a greater reduction in strength after 48 h of degradation in comparison to samples statically corroded. It was found that thicker micro-tensile samples (h > 200 μm) had a greater loss of strength in comparison to its thinner counterpart (h less then 200 μm), due to increased corrosion of the thicker samples (203 MPa versus 260 MPa after 48 h, p = 0.0017). This investigation emphasizes the necessity of implementing physiologically relevant testing conditions, including dynamic corrosion and stent strut thickness, when evaluating potential biomaterials for biodegradable stent application.Drug resistance and relapse after treatment of visceral leishmaniasis (VL) with the chemotherapeutic drugs has impeded the VL elimination programme especially, in the endemic region of Bihar, India. Currently, Antimonials (Sbv) have been rendered obsolete (Bihar) as frequent treatment failure and relapse in Sbv treated patient’s warrants greater vigilance and attention to the limited drugs. A clinical isolate of L.donovani obtained from an Amphotericin B (AmB) relapse patient was evaluated for its susceptibility to AmB and a hyperlipidemic drug Guggul. The evaluation of susceptibility or resistance to any drug still relies on in vitro assay on promastigote and amastigote stages of Leishmania spp. as there are no validated markers which can ascertain drug resistance in Leishmania. The anti-promastigote effect of AmB and Guggul were demonstrated by significant cellular and morphological changes exhibiting apoptosis-mediated cell death. To further illustrate the molecular mechanism of the parasite’s response upon exposure to either AmB and Guggul, sequential window acquisition of all theoretical fragment ion spectra mass spectrometry (SWATH-MS) for quantitative proteomics analysis was performed along with computational data analysis; revealing considerable differences in the proteome profiles which could be regarded as putative markers for resistance or drug targets for development of therapeutic antileishmanials.

To characterize patient and counselor satisfaction with structured, tier-based contraceptive counseling provided by a nonclinician.

We conducted a planned secondary analysis of patient and counselor surveys from a study that enrolled women in 2 contraceptive care programs. All participants received structured contraceptive counseling from trained staff members. Women and counselors completed a confidential post-visit survey regarding satisfaction with counseling and medical mistrust. We used univariate and multivariable regressions to examine differences in high satisfaction with counseling (top score), perceived counselor influence, and perceived counselor judgment by participant characteristics.

Nine hundred forty-two participants completed surveys; most reported they felt respected (100.0%), trusted the counseling information (99.5%), and that counseling helped them choose a contraceptive method (83.8%). Black race, high school education, public insurance, an income below the federal poverty level, aigh medical mistrust were less likely to report high levels of satisfaction and more likely to report perceived influence or judgment from the counselor.

Overall, women reported high satisfaction with tier-based contraceptive counseling delivered by a nonclinician in 3 federally qualified health centers. However, women with high medical mistrust were less likely to report high levels of satisfaction and more likely to report perceived influence or judgment from the counselor.

To compare the overnight maximum pain scores after osmotic dilator placement prior to a dilation and evacuation (D&E) procedure in participants assigned to a prescription for ibuprofen alone or to ibuprofen plus oxycodone.

We conducted a nonblinded pragmatic, randomized controlled trial to evaluate pain management among women undergoing osmotic dilator placement prior to D&E. We randomly assigned 70 participants at 12 weeks 6 days to 23 weeks 6 days gestation to receive a prescription for ibuprofen alone, or ibuprofen plus oxycodone. We assessed pain using a numeric rating scale (NRS; scale 0-10) at the following time points Baseline, dilator placement, 2 and 6 hours, and preoperatively, where we also asked participants their maximum pain score. The primary outcome was mean individual NRS pain score change from baseline to maximum pain score.

Maximum mean pain score (change from baseline) was 4.7 ± 2.9 in the ibuprofen group, and 6.5 ± 2.5 in the ibuprofen plus oxycodone group (p < 0.01). Parescriptions did not appear to reduce overnight pain, minimizing these prescriptions would avoid opioid exposure for patients undergoing D&E.Protein remote homology detection and protein fold recognition are two important tasks in protein structure and function prediction. There are three kinds of methods in this field, including the discriminative methods, the alignment methods, and the ranking methods. In this study, a new discriminative method called ReFold-MAP is proposed. The proposed method extracts comprehensive features based on three profile-based features Motif-PSSM, ACC-PSSM, and PDT-profile. We call these features as MAP features, which incorporate the structural motif kernel information, the evolutionary information, and the sequence information. The experiments prove that ReFold-MAP outperforms other approaches. Therefore, ReFold-MAP will be a useful tool for protein remote homology detection and fold recognition.A new procedure for direct extraction and analysis of sulfonamides residues in bovine liver was developed. Briefly, an amount of homogenized sample was mixed with sand and incubated in an ultrasonic bath to promote tissue disruption. After, samples are centrifuged in an empty cartridge with a fritted glass filter. The filtrate was diluted with acetonitrile to precipitate proteins and centrifuged again. The final supernatant was diluted with HPLC mobile phase (ammonium acetate 10 mM methanol, 8515) and analyzed with a LC-MS/MS system with electrospray ionization in positive mode. Six sulfonamides were studied, and the procedure showed good recoveries values for all analytes, except for sulfamethoxazole and sulfaquinoxaline. Sulfapirydine was used as internal standard. C75 Consumption of organic solvents was restricted to 2 mL of acetonitrile per sample.

In advanced lung cancer, precision medicine requires repeated biopsies via bronchoscopy at therapy change. Since bronchoscopies are often stressful for patients, sedation using both fentanyl and midazolam is recommended in Europe and America. In Japan, bronchoscopies are generally orally performed under midazolam and oropharyngeal anesthesia. Nasal intubation creates a physiological route to the trachea, causing less irritation to the pharynx than intubation via the oral cavity; however, the necessity of oropharyngeal anesthesia remains unclear. We aimed to compare the safety, patient discomfort, and diagnostic rates for oropharyngeal anesthesia and sedation with pethidine and midazolam (Group A) and sedation with midazolam and fentanyl without oropharyngeal anesthesia (Group B) for ultrathin bronchoscopy of peripheral pulmonary lesions (PPLs) via nasal intubation.

We retrospectively reviewed 74 consecutive potential lung cancer patients who underwent ultrathin bronchoscopies at the Hakodate Goryoukaku Hospital between July 2019 and June 2020. We reviewed the following diagnostic rates; cumulative doses of lidocaine, midazolam, and fentanyl; hemodynamic changes; procedural complications in both groups. Pharyngeal anesthesia in group A was administered by spraying 2% (w/v) lidocaine into the pharynx. The chi-squared test was used for statistical analyses.

There were no significant changes in hemodynamic parameters and complications. The mean level of discomfort for bronchoscopic examinations was significantly lower in Group B (2.39 vs. 1.64; P=0.014), with no significant inter-group difference in the diagnostic yields for PPLs (63.0% vs. 71.4%; P=0.46).

Our findings indicate the advantages of sedation with fentanyl and midazolam without oropharyngeal anesthesia for ultrathin bronchoscopy through nasal intubation.
