Characterization of human infiltrating and circulating gamma-delta T cells in prostate cancer
2019
Purpose The aim of our study was to prospectively evaluate the distribution of gamma-delta (γδ)1 and γδ2 T cells and their phenotypes in peripheral blood and prostate samples of patients diagnosed with or without prostate cancer (PCa) at prostate biopsy. Materials and methods A consecutive series of 43 outpatients underwent trans-rectal echo-guided prostate biopsy for suspected PCa. Flow cytometry analysis was used to identify and characterize the γδ T cells populations in peripheral blood and tissue samples. Patients were stratified according to the presence or not of PCa, and its International Society of Urological Pathology (ISUP) grade (1 vs. ≥2). Results The distribution of γδ T cells …
Sexual dysfunctions after transurethral resection of the prostate (TURP): evidence from a retrospective study on 264 patients
2015
Objectives: Benign prostatic hyperplasia (BPH) and sexual dysfunctions are diseases with a high prevalence in aged men. Several studies have found a link between BPH and LUTS resulting from deterioration in sexual function in men aged 50 years and older for whom TURP is considered the gold standard. The impact of TURP on sexual functions still remain uncertain, nor is it clear what pathophysiological mechanism underlying the emergence of new episodes of Erectile Dysfunction (ED) following TURP in patients with normal sexual function before surgery, while retrograde ejaculation and ejaculate volume reduction represent a clear side effect; derived from BPH treatment. The aim of this study was…
Computer-assisted sperm morphometry fluorescence-based analysis has potential to determine progeny sex
2016
This study was designed to determine the ability of computer-assisted sperm morphometry analysis (CASA-Morph) with fluorescence to discriminate between spermatozoa carrying different sex chromosomes from the nuclear morphometrics generated and different statistical procedures in the bovine species. The study was divided into two experiments. The first was to study the morphometric differences between X- and Y-chromosome-bearing spermatozoa (SX and SY, respectively). Spermatozoa from eight bulls were processed to assess simultaneously the sex chromosome by FISH and sperm morphometry by fluorescence-based CASA-Morph. SX cells were larger than SY cells on average (P < 0.001) although with impo…
Association between IgM Anti-Herpes Simplex Virus and Plasma Amyloid-Beta Levels.
2011
International audience; OBJECTIVE: Herpes simplex virus (HSV) reactivation has been identified as a possible risk factor for Alzheimer's disease (AD) and plasma amyloid-beta (Aβ) levels might be considered as possible biomarkers of the risk of AD. The aim of our study was to investigate the association between anti-HSV antibodies and plasma Aβ levels. METHODS: The study sample consisted of 1222 subjects (73.9 y in mean) from the Three-City cohort. IgM and IgG anti-HSV antibodies were quantified using an ELISA kit, and plasma levels of Aβ(1-40) and Aβ(1-42) were measured using an xMAP-based assay technology. Cross-sectional analyses of the associations between anti-HSV antibodies and plasma …
Schistosomal appendicitis: Case series and systematic literature review
2021
Background Globally, schistosomiasis affects at least 240 million people each year with a high proportion of cases in sub-Saharan Africa. The infection presents a wide range of symptoms mainly at the gastrointestinal and urogenital level. Cases of schistosomiasis-related appendicitis are seldom reported. The aim of the present study is to identify the prevalence of schistosomiasis-related appendicitis in Beira, Mozambique and compare to global prevalence. Methods We retrospectively reviewed all cases of appendicitis recorded from January 2017 to March 2020 at a single pathology department located in Beira in order to assess the prevalence of schistosomiasis. Moreover, we performed a systema…
Morphometry and subpopulation structure of Holstein bull spermatozoa: variations in ejaculates and cryopreservation straws
2016
Artículo científico Sperm quality is evaluated for the calculation of sperm dosage in artificial reproductive programs. The most common parameter used is motility, but morphology has a higher potential as a predictor of genetic quality. Morphometry calculations from CASA‑Morph technology improve morphological evaluation and allow mathematical approaches to the problem. Semen from 28 Holstein bulls was collected by artificial vagina, and several ejaculates were studied. After general evaluation, samples were diluted, packaged in 0.25 ml straws, and stored in liquid nitrogen. Two straws per sample were thawed, and slides were processed and stained with Diff‑Quik. Samples were analyzed by a CA…
Sperm kinematic, head morphometric and kinetic-morphometric subpopulations in the blue fox (Alopex lagopus)
2016
This work provides information on the blue fox ejaculated sperm quality needed for seminal dose calculations. Twenty semen samples, obtained by masturbation, were analyzed for kinematic and morphometric parameters by using CASA-Mot and CASA-Morph system and principal component (PC) analysis. For motility, eight kinematic parameters were evaluated, which were reduced to PC1, related to linear variables, and PC2, related to oscillatory movement. The whole population was divided into three independent subpopulations: SP1, fast cells with linear movement; SP2, slow cells and nonoscillatory motility; and SP3, medium speed cells and oscillatory movement. In almost all cases, the subpopulation dis…
Sonographic biometry in obstructive uropathy of children: preoperative diagnosis and postoperative monitoring.
1985
Renal sonography was performed in 92 children with obstructive uropathy or vesicoureteral reflux preoperatively and at follow-up. Renal volume and the anteroposterior diameter of the renal pelvis proved to be the most reliable morphometric criteria for objective sonographic staging and follow-up of urinary tract obstruction. If transient obstruction occurred after uncomplicated antireflux ureterovesico-plasties (n = 41), it lasted at most 4 weeks. Kidneys with transient postoperative ureterovesical junction obstruction (n = 21) reverted to normal sonographic pattern within 4 weeks following ureteral reimplantation. In cases of ureteropelvic junction obstruction (n = 30), it took up to 6 mon…
The importance of potassium citrate and potassium bicarbonate in the treatment of uric acid renal stones
2017
Uric acid calculi can also be treated without surgery, with simple medical lytic therapy. After appropriate dietary adjustments and add of mineral water, the needed amount of alkali supplementation can increase pH values of the urine in order to dissolve the stones. Treatment should be prolonged to prevent stone recurrence. A case of bilateral renal uric acid stones that were successfully treated by alakalizing treatment was presented.
Prognostic evaluation of biofeedback response in patients treated for anorectal malformation
2015
Abstract Purpose Functional bowel outcome in patients with anorectal malformation often is poor. For fecal incontinence resulting from sphincter dysfunction, biofeedback (BFB) training appears to be effective. The aim of study was to investigate the bowel function in incontinent children treated for ARM, using a clinical score, a manometric and pelvic magnetic resonance evaluation, in order to establish predictive parameters of response after BFB. Methods 25 children (median age of 6.5years) with true fecal incontinence were evaluated by clinical score, anorectal manometry and magnetic resonance imaging (MRI). According to these evaluations patients were divided in 4 groups: group 1 (favora…
