Higher production of MCP-1 could be responsible for the increased accumulation of Mvarphi in women with SMM and IMM. The augmented inflammatory reaction in endometrium and increased PGF2alpha levels might be detrimental to reproductive outcome in women with SMM or IMM.

Although human papillomavirus (HPV) 16 is the cause of cervical cancer in most countries including Japan, the involvement of cervical cancer with HPV types in Mongolian and Myanmar populations is largely unknown. We examined the expression of HPV in formalin-fixed and paraffin-embedded cervical tissues from 40 Japanese, 32 Mongolian, and 30 Myanmar cervical cancer patients. We performed immunohistochemistry using anti-HPV16 and anti-HPV 1, 6, 11, 16, 18 and 31 cocktail and then correlated it with the expression of Ki-67 and p63. HPV 16 was detected in 72%, 65% and 50% of Japanese, Mongolian and Myanmar cervical cancer patients, respectively, whereas 5 (13%) of the 40 patients, 8 (25%) of the 32 patients and 7 (23%) of the 30 patients in HPV 16-negative cancers were positive for other HPV types included in the cocktail, respectively. Ki-67 labeling index (LI) as well as p63 LI was significantly higher in HPV 16-positive patients than in HPV 16-negative ones in the Japanese and Mongolian samples. p63 expression was significantly associated with stage III and IV in Japan and Mongolia. These findings suggest that HPV 16 may be associated with cell proliferative activity and tumor progression, possibly depending upon the expression of p63 in the cervical cancer. In addition, immunohistochemical detection for distinguishing the type of HPV may also be useful for cervical cancer in the clinical setting.

Sarcopenia, the degenerative and systemic loss of skeletal muscle mass, is a multifactorial syndrome reflecting frailty, poor general health status, and the possible presence of cancer cachexia. Here, we aimed to investigate the effect of sarcopenia on the efficacy of pembrolizumab in patients with advanced urothelial carcinoma (aUC). This retrospective study included 28 patients with aUC treated with pembrolizumab as a second or later-line therapy. Sarcopenia was determined based on computed tomography images. Associations of sarcopenia with objective response rate (ORR), progression-free survival (PFS), and overall survival (OS) were evaluated. In total, 19 (68%) patients had sarcopenia. ORR was 21% in the patients with sarcopenia, while those without sarcopenia showed significantly higher ORR (67%, P = 0.019). PFS was significantly shorter in patients with sarcopenia than in those without (median, 3 vs. 15 months, P = 0.038). Although the statistical significance was not reached, OS was shorter in patients with sarcopenia than in those without (median, 7 months vs. not reached; P = 0.086). Our preliminary results demonstrated that more than half of patients with aUC who received pembrolizumab had sarcopenia, which was significantly associated with poor therapeutic efficacy. This indicates the clinical relevance of sarcopenia in pembrolizumab therapy for patients with aUC.

Apart from increased stress urinary incontinence, there was an improvement in overall urinary function in terms of patient-reported symptoms and urodynamics, despite deep vesicovaginal space dissection. Hence, LSC is a viable surgical option for pelvic organ prolapse, restoring both level 1 and level 2 support without detrimental effects on urinary function.

Metastasis from renal cell carcinoma (RCC) to the testis is rare. This case report presented an extremely rare case of simultaneous bilateral testicular metastases from RCC in a 65-year-old man who had experienced indolent scrotal enlargement over a period of several months. Scrotal ultrasonography showed 4.0- and 2.0-cm-sized masses in the left and right testes, respectively. Contrast-enhanced computed tomography identified multiple tumors in the kidneys, the pancreas and the left adrenal gland. Left orchiectomy and pathological examination were performed and indicated testicular metastasis from clear cell RCC. The patient underwent complete surgical resection of all residual lesions. Postoperative follow-up examination without adjuvant therapy identified no recurrence over 11 months. This study also reviewed existing literature and determined that retrograde venous spread from the primary kidney tumor to the testis may be an important pathway for testicular metastasis from RCC. In conclusion, RCC can result in testicular metastases not only unilaterally, but also bilaterally, as was observed in the present case.

BackgroundThe purpose of this work was to investigate whether clinical cytology could be useful in the preoperative diagnosis of pelvic actinomycosis.MethodsThis study involved the prospective collection of samples derived from the endometrium and the uterine cervix, and retrospective data analysis. Nine patients with clinically diagnosed pelvic actinomycosis were enrolled. The clinical and hematological characteristics of patients were recorded, and detection of actinomyces was performed by cytology, pathology, and bacteriological culture of samples and by imprint intrauterine contraceptive device (IUD) cytology.ResultsThe detection rate of actinomyces was 77.7% by combined cervical and endometrial cytology, 50.0% by pathology, and 11.1% by bacterial culture.ConclusionThe higher detection rate of actinomyces by cytology than by pathology or bacteriology suggests that careful cytological examination may be clinically useful in the preoperative diagnosis of pelvic actinomycosis.

Streptomyces sp Mo endo-β-1,3-glucanase was found to have hydrolyzing activity toward curdlan and released laminarioligosaccharides selectively. The molecular weight was estimated to be 36000 Da and its N-terminal amino acid sequence was VTPPDISVTN. The optimal pH was 6 and the enzyme was found to be stable from pH 5 to 8. The optimal temperature was 60 °C and the activity was stable below 50 °C. The enzyme hydrolyzed selectively curdlan containing only β-1,3 linkages. The enzyme had 89% relative activity toward Laminaria digitata laminarin, which contains a small amount of β-1,6 linkages compared with curdlan, while Eisenia bicyclis laminarin with a higher amount of β-1,6-linkages, was not hydrolyzed. Mo enzyme adsorbed completely on curdlan powder. The enzymatic hydrolysis of curdlan powder resulted in the accumulation of laminaribiose (yield 81.7%). Trisaccharide was inevitably released from the hydrolysis of laminarioligosaccharides with 5 to 7 degrees of polymerization (DP). Although the enzyme cleaved off disaccharide (DP 2) from tetrasaccharide (DP 4), the reaction rate was lower than those of DP 5 to 7. The results indicated that the active site of Mo endo-β-1,3-glucanase can efficiently recognize glucosyl residue chain of greater than DP 5 and hydrolyzes the β-1,3 linkage between the 3rd and 4th glucosyl residue.
