Expression of VD metabolizing enzymes has not previously been investigated in human testis and male reproductive tract. Therefore, we performed a comprehensive analysis of the expression of VDR, VD activating (CYP2R1, CYP27A1, CYP27B1) and inactivating (CYP24A1) enzymes in the testis, epididymis, seminal vesicle (SV), prostate and spermatozoa.\n\nTissue samples were obtained after orchiectomy (testis n = 13; epididymis n = 7), prostatectomy Navitoclax concentration (prostate n = 5 and SVs n = 3) and semen samples obtained after ejaculation (n = 13). mRNA was detected with RT-PCR and expression

of proteins was determined by immunohistochemistry.\n\nVDR and VD metabolizing enzymes were concomitantly expressed in round and elongated spermatids, vesicles within the caput epididymis, and glandular epithelium of cauda epididymis, SV and prostate. The expression pattern in ejaculated spermatozoa varied,

although, concomitant expression of VDR, CYP2R1, CYP27B1 and CYP24A1 was observed in neck and midpiece in a subpopulation of mature spermatozoa.\n\nOn the basis of the marked expression of VDR and the VD metabolizing enzymes in human testis, ejaculatory tract and mature spermatozoa, we suggest that VD is important for spermatogenesis and maturation of human spermatozoa.”
“Background: Small intestinal bacterial overgrowth (SIBO) may mimic a functional disorder such as irritable bowel syndrome (IBS) or functional bloating (FB). In this Study, 3 MA we buy LY2606368 aimed to assess the utility of glucose breath test (GBT) in patients with the above conditions.\n\nMethods: This study included 200 consecutive patients (130 with IBS and 70 with FB on the basis of Rome III criteria) and 70 controls with similar age and sex distribution. Patients and controls underwent 50g GBT and a H(2) peak of >= 12 ppm was considered diagnostic of SIBO. Positive patients received rifaximin of 1200 mg/day for 10 days and underwent a second GBT I month after the end of treatment. A symptom questionnaire was completed before and after therapy.\n\nResults:

GBT resulted to be altered in 21 out of 130 IRS patients and in 2 out of 70 FB patients with a significant difference of the former group compared with controls (3 out of 70, P = 0.0137). Most IRS patients with a positive GBT complained of diarrhea. GBT showed an increased methane excretion in 26% of patients. Who Were equally distributed among different bowel pattern subgroups. Previous abdominal surgery was more frequently seen in GBT-positive patients (P = 0.008). After antibiotic treatment, eradication of SIBO was achieved in 70% of patients, with a significant improvement of symptoms in eradicated patients compared with the not eradicated ones (P < 0.001).\n\nConclusions: GBT is useful to identify a subgroup of IBS-like patients, whose symptoms are owing to SIBO.
