The aim of the present study was to evaluate the effects of exogenous oxytocin and PGF2a on seminal quality and libido sexualis in bucks. To investigate the role of these hormones on male fertility, semen samples from 20 Norduz bucks (3-4 years of age) were collected with an artificial vagina twice a week with five replications in breeding season. Bucks were randomly assigned to five groups, control group was administered with 2 mL of sodium chloride, 0.9% (w/v)) i.m., whilst the experimental groups were administered with oxytocin 10 IU, i.v. (Group 1, n = 5), oxytocin 20 IU, i.v. (Group 2, n = 5), PGF2a 5 mg, i.m. (Group 3, n = 5) or PGF2a 10 mg, i.m. (Group 4, n = 5) 20 min before each collection. There was no statistical difference between the treatment groups in terms of motility (P>0.05). However, semen volume, concentration, abnormal spermatozoa rate, intact membrane rate and libido results were statistically significant among the different groups (P<0.05). As a result, administration of 20 IU oxytocin twenty minutes prior to semen collection in bucks did not improve overall semen quality, however, libido, semen volume, and sperm concentrations were increased. In contrast to oxytocin, PGF2a administration has led to a slight decrease in libido and has shown moderate effects on semen quality. [ABSTRACT FROM AUTHOR]

Prostaglandin F2α (PGF2α) and oxytocin have been used to improve reproductive performance in many mammalian species, including humans. The aim of the present study was to determine their effects on sperm quality when extended stallion semen was enriched with PGF2α or oxytocin. In this study, 16 healthy adult stallions, each 15-22 years old, were used. Five ejaculates from each stallion were collected with an artificial vagina during breeding season. Thereafter, gel-free semen was divided into 7 aliquots and diluted with an INRA96 semen extender. The following different treatments were evaluated: 3 with only PGF2α (10, 20, and 40 µg/mL) and 3 with only oxytocin (2, 3, and 4 IU/mL). Sperm quality was evaluated before and after applying the different treatments. In vitro addition of oxytocin to semen did not show improvement in any of the sperm quality parameters measured. However, sperm supplementation with 40 µg of PGF2α caused a significant increase (P < 0.05) in diluted semen motility. We concluded that the addition of PGF2α to elder stallions' semen may help maintain sperm motility. Future research might assess the effects of PGF2α on fertility. Our results were based on in vitro evaluations, and thus further fertility trials are required. [ABSTRACT FROM AUTHOR]

Objectives: To investigate the factors influencing progression and chronification of episodic migraine, we conducted a 12-month face to face follow-up study of episodic migraine patients. Methods: One hundred eighty patients with episodic migraine were enrolled. 120 parameters were analyzed including demographic factors, social and life-style features, comorbid medical illnesses and headache characteristics. After the first evaluation, all patients was scheduled to a structured face to face interview at 3-months interval for one-year. Results: Thirty-two (17,7%) patients developed chronic daily headache. Four out of 32 (2,2%) had definite chronic migraine. Low education level, obesity, greater tea consumption (>= 4 cups/daily), predominantly hot and spicy diet, high headache frequency, long duration of headache and presence of allodynia at baseline, and more days with symptomatic drug intake were significant risk factors for progression and chronification of migraine. Cox regression analysis revealed triptan and NSAID intake, hot and spicy eating habit and allodynia as risk factors for chronification. Conclusion: Higher amount of tea consumption, hot and spicy diet appeared to be new risk factors for chronification of migraine. Weight gain is one of the most important risk factors. Patients should be warned about the risk factors to prevent chronification. Epizodik migrenin kronikleşmesinde ve progresyonunda rolü olabilecek faktörleri araştırmak amacı ile epizodik migrenli hastaların 12 aylık yüz yüze takip çalışmasını gerçekleştirdik. Gereç ve yöntem: 180 epizodik migren hastası çalışmaya alındı. Demografik verileri, sosyal yaşam ve yaşam tarzı özellikleri, eşlik eden hastalıklar ve başağrısı özellikleri olmak üzere 120 parametre analiz edildi. İlk değerlendirmeyi takiben tüm hastalar bir yıl boyunca 3 ayda bir yüz yüze yapılandırılmış görüşmeye alındı. Bulgular: Otuz iki (17,7%) hastada kronik migren gelişti. Otuz iki hastanın dördüne (%2.2) kesin kronik migren tanısı kondu. Düşük eğitim seviyesi, obezite, yüksek miktarda çay tüketimi (≥4 bardak/gün), acılı ve baharatlı beslenme tarzı, yüksek başağrısı frekansı, uzun süreli başağrısı hikayesi, ilk değerlendirmede allodini varlığı ve fazla miktarda semptomatik ilaç alınması migrenin kronikleşmesi ve progresyonu için anlamlı risk faktörleri olarak J.Neurol.Sci.[Turk] 2 saptandı. Cox-regresyon analizinde fazla miktarda triptan ve NSAID alımı, acılı ve baharatlı beslenme tarzı ve allodini varlığı anlamlı risk faktörleri olarak bulundu. Sonuç: Fazla miktarda çay tüketimi, acılı ve baharatlı beslenme migrenin kronikleşmesi ve progresyonunda yeni risk faktörleri olarak ortaya kondu. Kilo alımı en önemli risk faktörlerinden biridir. Hastalar migrenin kronikleşmesinin ve progresyonunun önlenmesi için risk faktörleri konusunda uyarılmalıdırlar

- Abstract
Objectives: The aim of this study was to evaluate
18 F-fluoro-2-deoxy-glucose (FDG) uptake patterns in primary tumors and metastatic lesions, and also to assess the diagnostic contribution of positron emission tomography/computed tomography (PET/CT) in the initial staging of gastric cancer (GC)., Methods: The total number of 341 patients with GC were included in this study. All18 F-FDG PET/CT imagings were performed for initial staging. The maximum standardized uptake value (SUVmax ) of primary tumor, obtained from18 F-FDG PET/CT imaging was compared between subtypes of GC., Results: Mean SUVmax of 339 patients’ primary tumor was 12.9±8.6. The highest mean SUVmax was detected in patients with medullary subtype GC (17.8±9.9) while the lowest mean SUVmax (9.7±7.6) was seen in signet ring cell carcinoma (SRCC). The primary mean SUVmax was found statistically higher in tubular adenocarcinoma (TAC) group than SRCC group (p<0.001). Higher SUVmax values were found statistically significantly correlated with advanced age (aged ≥60) and increased tumor size (>3 cm) in patients with TAC (p=0.03). Primary tumor SUVmax was found statistically higher in regional lymph node (RLN) positive patients than in RLN negative patients in TAC and SRCC groups (p<0.001 and p=0.012, respectivelly). Also, in patients with SRCC, SUVmax was significantly higher in the distant metastatic group than in the group without metastasis (p=0.025)., Conclusion: Increased primary tumor SUVmax was associated with some of clinical parameters such as age and RLN metastasis in patients with TAC. However, there was no relationship between distant metastatic state and primary tumor18 F-FDG uptake in TAC. However, high SUVmax of primary tumor in SRCC was associated with regional and distant metastasis, and primary tumor18 F-FDG uptake may be a prognostic value for this subgroup.- Published
