Multiple myeloma (MM) is the second most common hematological malignancy. It is characterized by abnormal transformation and uncontrolled clonal proliferation of malignant plasma cells in the bone marrow (BM), which can destroy bone structure and inhibit hematopoiesis. Although there are new therapeutic methods, they are not curative, mainly because it is difficult to deliver an effective amount of drug to BM, leading to a failure to eradicate MM cells inside the BM. BM homing is an important and unique characteristic of MM cells and it is mainly affected by surface molecules on the tumor cell membrane. Inspired by this mechanism, an MM-mimicking nanocarrier is developed by coating bortezomib (BTZ)-loaded poly(ε-caprolactone)-poly(ethylene glycol)-poly(ε-caprolactone) (PCEC) nanoparticles with the MM cell membrane. The MM-mimicking nanoparticles can enter the BM based on BM homing as a "Trojan horse" and target the tumor cells through homologous targeting. In this way, drug availability at the myeloma site is enhanced so as to inhibit MM growth. In addition, these MM-mimicking nanoparticles can escape phagocytosis by the MPS and have a long circulation effect. The in vivo therapeutic results demonstrate an excellent treatment efficacy for MM. Accordingly, this strategy may be a promising platform for the treatment of MM.

Woodhouse-Sakati syndrome is a rare autosomal recessive disease with endocrine and neuroectodermal aberrations with heterogeneous phenotypes and disease course. The most common phenotypes of the disease are progressive sensorineural hearing loss and alopecia, mild-to-moderate mental retardation and hypogonadism. The disease results from mutations in the DCAF17 gene.

Here, we reported a large consanguineous pedigree with multiple affected individuals with Woodhouse-Sakati syndrome phenotypes. Laboratory tests confirmed the endocrine perturbance in affected individuals. To find out the underlying genetic change, whole-exome sequencing was carried out.

Analysis of the exome data identified a splicing-site deletion NM_025000.3c.1423-1_1425delGACA in DCAF17 gene. Sanger sequencing confirmed the co-segregation of the variant with the disease phenotypes in the family.

The variant is predicted to cause aberrant splicing, i.e., exon skipping, resulting in the translation of a truncated functionless protein which results in appearance of typical phenotypic features and clinical laboratory findings of Woodhouse-Sakati syndrome in affected members of the family.

In the present study, three angiotensin-I converting enzyme (ACE-I) inhibitory peptides [Ala-Pro-Asp-Gly (APDG), Pro-Thr-Arg (PTR), and Ala-Asp (AD)] were isolated and characterized from ribbonfish protein hydrolysate (RFPH) and described their mechanism of action on ACE activity. As per the results, peptide PTR showed ≈ 2 and 2.5-fold higher enzyme inhibitory activity (IC50 = 0.643 ± 0.0011 μM) than APDG (IC50 = 1.061 ± 0.0127 μM) and AD (IC50 = 2.046 ± 0.0130 μM). Based on experimental evidence, peptides were used for in silico analysis to check the inhibitory activity of the main protease (PDB 7BQY) of SARS-CoV-2. The results of the study reveal that PTR (-46.16 kcal/mol) showed higher binding affinity than APDG (-36.80 kcal/mol) and AD (-30.24 kcal/mol) compared with remdesivir (-30.64 kcal/mol). Additionally, physicochemical characteristics of all the isolated peptides exhibited appropriate pharmacological properties and were found to be nontoxic. Besides, 20 ns molecular dynamic simulation study confirms the rigid nature, fewer confirmation variations, and binding stiffness of the peptide PTR with the main protease of SARS-CoV-2. Therefore, the present study strongly suggested that PTR is the perfect substrate for inhibiting the main protease of SARS-CoV-2 through the in silico study, and this potential drug candidate may promote the researcher for future wet lab experiments.

Cytoscopic-guided laser ablation (CLA) is a technique that can be used to correct intramural ectopic ureters (EUs) in dogs.

To describe clinicopathologic, imaging, and cystoscopic findings in dogs undergoing CLA for intramural EU correction, and whether any of these findings are associated with continence outcomes.

Thirty-one client-owned dogs undergoing CLA between 2009 and 2019.

Retrospective cohort study. Data collected from medical records included signalment, clinical findings (including continence score at presentation), clinicopathologic findings (serum biochemistry profile, urinalysis, and urine culture results before CLA), ultrasonography, and cystoscopy findings. GW5074 chemical structure Follow-up information was collected at 1 day to 1week, 1week to 1month, and at >1month time points after CLA. Final continence score was determined based on this follow-up information. Multiple logistic regression was used to determine factors that were associated with final continence score.

Through mycelial microscope observation and strain identification of pathogenic fungus MS-3, it was determined to be R. solani AG-5. Both 5' and 3' rapid amplification of cDNA ends were used to clone the serine protease gene RsSLP from R. solani AG-5. The full-length obtained for RsSLP was 1714 bp with an open reading frame of 1587 bp, encoding a protein of 528 amino acids with a molecular mass of 55.8 kDa. This protein contained a predicted signal peptide for secretion but lacked a transmembrane domain or membrane anchor site. Bioinformatics analysis identified this protein as a serine protease with the Peptidase_S8 and Inhibitor_I9 characteristic domains of SLPs. Phylogenetic analysis suggested that frequent gene duplications of the SLPs occurred in R. solani (RsSLP), and RsSLP shares characteristic sequence features with virulence factors of other phytopathogenic fungi. Because the secretory serine protease RsSLP from R. solani AG5 is similar to the virulence factors of other phytopathogenic fungi, its identification will be helpful in studies considering the roles of these proteases in pathogen virulence.

Malnutrition, as determined by the Controlling Nutritional Status (CONUT), has an effect on the 3-month and long-term prognosis of stroke patients. The association between malnutrition and in-hospital mortality has not been well established. We aimed to investigate the relationship between the CONUT score on admission and in-hospital mortality and length of stay (LOS) in elderly patients with acute ischemic stroke (AIS).

This study analyzed controls and patients with AIS. Malnutrition was determined using the CONUT score. A CONUT score of 5-12 was defined as undernutrition status. Based on the CONUT scores, the patients were divided into the low CONUT (0-4) and high CONUT (5-12) groups.

In total, 1079 participants were recruited, comprising 288 controls and 791 AIS patients. Among the 791 patients, 64 (8.1%) had malnutrition and 63 (7.9%) had an in-hospital death. Compared to the controls, the AIS patients presented higher CONUT scores, higher proportion of in-hospital mortality (8.0%), and longer length of stay. Malnutrition was independently associated with in-hospital mortality in the AIS patients (adjusted odds ratio 3.77, 95% confidence interval [CI] 1.55-9.15; p=0.003). The general linear models showed an association between the CONUT score and LOS (β=0.574, 95% CI 0.208-0.934; p=0.002). Furthermore, the effect of the interaction between infection and nutrition status on in-hospital mortality showed borderline statistical significance (p=0.06).

Malnutrition estimated by the CONUT score on admission can be a predictor of in-hospital mortality and increased LOS in elderly AIS patients.

Specifically, neurotization options have not been explored. To address this deficiency in the literature, the current cadaveric feasibility study was performed. Via a transgluteal approach on 16 cadaveric sides, the proximal sciatic nerve and the entrance of the SGN into the gluteus medius and minimus were identified. Additionally, branches from the sciatic nerve to the hamstring muscles were traced proximally to confirm their position in relation to the sciatic nerve as a whole. These branches were cut at the level of the ischial tuberosity and teased away from the sciatic nerve proximally to the greater sciatic foramen and transferred superolateral to the SGN. The diameter of each nerve branch was measured as well as its available length for reaching the SGN. All branches of the sciatic nerve to the hamstring muscles arose from the anteromedial part of the nerve. The mean diameters of the branches to the semimembranosus, semitendinosus, and biceps femoris muscles were 2.1, 1.9, and 1.5 mm, respectively. The mean diameter of the SGN was 3.1 mm and the mean distance from this entrance point to the ischial spine was 7.2 cm. The mean length of the donor nerve was 8.5 cm. Based on our study, use of a tibial-innervated hamstring branch as a donor for nerve transfer to the SGN is feasible.

There is a remodeling of the central airways in horses with severe asthma but whether a similar process occurs in horses with the mild or moderate asthma (MMA) is unknown.

To evaluate lesions affecting the central airways of horses with MMA.

Twelve horses with MMA and 8 control horses.

Case-control retrospective study of horses classified as MMA affected or controls based on history and bronchoalveolar lavage fluid cytology. Endobronchial biopsies were analyzed using histomorphometry and a semiquantitative histologic scoring system.

Histomorphometry identified epithelial hyperplasia (47 μm

/μm [34-57 μm

/μm]; P=.02), a thickened lamina propria (166 μm [73-336 μm]; P=.04), and smooth muscle fibrosis (42% [33%-78%]; P=.04) in horses with MMA when compared to controls horses (24 μm

/μm [21-80 μm

/μm]; 76 μm [36-176 μm]; and 33% [26%-52%], respectively). The semiquantitative score results indicated, in horses with MMA, the presence of epithelial hyperplasia (7 of the 12 horses with MMA and only 1 of the 8 control horses had a score of 1/1), and submucosal inflammatory leucocytes in the central airway (11 of the 12 horses with MMA and only 4 of the 8 control horses had a score ≥ 1/2).

Tissue remodeling of the bronchial lamina propria, epithelium, and smooth muscle was present in horses with MMA.
