Although bariatric surgery is a safe and effective procedure in the treatment of adolescent morbid obesity, long-term data is scarce regarding its nutritional and developmental complication in this growing population of patients.

Cancer is the second leading cause of death globally. piRNAs, which are a novel type of identified small noncoding RNA (ncRNA), play a crucial role in cancer genomics. In recent years, a relatively large number of studies have demonstrated that several piRNA are aberrantly expressed in various kinds of cancers including gastric cancer, bladder cancer, breast cancer, colorectal cancer and Lung cancer and may probably serve as a novel therapeutic target and biomarker for cancer treatment. The present review summarized current advances in our knowledge of the roles of piRNAs in cancer.

The goal of this study is to compare the response rate and the recurrence rate of available therapeutic modalities in the treatment of Idiopathic Granulomatous Mastitis (IGM). 374 patients with pathologically confirmed IGM, were included. They were subdivided into three levels of severity. Close observation had the best response rate with the lowest recurrence rate in mild to moderate cases. Severe cases were mostly treated by prednisolone or underwent surgery. The outcome of prednisolone use in severe cases was comparable to NSAIDs. Overall 9% were resistant to treatment and surgical intervention is still an option among them.

Axillary staging is one of the primary steps in management of Breast cancer patients. Current standard methods including blue dye and radicolloid have limitations and disadvantages. In this study, the feasibility of visualization of lymph node pathways and localization of SLN with the help of CEUS was assessed. 50 patients with early breast cancer diagnosis underwent CEUS and wire localization, methylenblue dye, and isotope scan methods for SLN detection. The pathology findings of the wired SLN were compared with those obtained from, methylenblue dye, and isotope scan methods. Lymph node wiring was successfully performed in 48 patients.Radio-isotope technique detected SLN in all 50 patients while blue-dye succeeded in 48. Sensitivity of CEUS to detect SLN compared with radio-isotope and blue dye methods was 96 % and 100 %, respectively. Considering costs and facilities required to perform radio-isotope technique and complications of blue dye we may accept CEUS with the help of micro-bubble contrasts as a viable alternative. However, more studies with larger sample volumes, using various drugs, and including non-selective population are warranted to better clarify feasibility and accuracy of this technique in comparison with current methods.

The possibility to replace or reduce rotifer use with a microparticle diet (MPD) from first feeding in yellowfin seabream larvae was investigated. The experiment consisted of five treatments, a rotifer (100%) control treatment (100R), three experimental treatments, which received a fixed ration of MPD supplemented with 75%, 50% and 25% of the amount rotifer fed in the control treatment (treatments 75R‐MPD, 50R‐MPD and 25R‐MPD respectively), and finally a treatment with the fixed MPD ration only (treatment 0R‐MPD). The results indicated that feeding regimes 100R, 75R‐MPD and 50R‐MPD did not differ significantly in the total length, final survival and stress test resistance. The highest dry weight was achieved in treatments 100R and 75R‐MPD at the end of the experiment compared with treatments 50R‐MPD, 25R‐MPD and 0R‐MPD. The 0R‐MPD treatment showed the lowest growth and survival. Yellowfin seabream larvae were able to ingest inert food directly from the moment of first feeding.

The objective of this experiment was to investigate the effect of fat supplementation during the transition period on pre and postpartum body weight (BW), body condition score (BCS), non-esterified fatty acids (NEFA), glucose and leptin concentrations in Holstein cows. Holstein cows (n = 15) received a low fat diet (LF; 1.61 Mcal net energy for lactation (NEL)/kg of dry matter [DM]), moderate fat diet (MF; 1.68 Mcal NEL/kg DM) or a high fat diet (HF; 1.74 Mcal NEL/kg DM) for 4 weeks prior to calving. All cows were fed similar lactation diets ad libitum (1.74 Mcal NEL/kg DM) for 30 days after calving. Increasing diet energy density during transition period had no effect on prepartum DMI, BCS, BW, glucose and NEFA concentrations (P > 0.05); but leptin concentrations and energy balance (EB) were affected by treatments (P < 0.05). Animals fed HF had less plasma leptin prepartum. After parturition, BW, milk production, milk fat, protein, urea nitrogen and plasma glucose concentrations were affected by prepartum diets (P < 0.05). Fat supplementation prepartum did not affect postpartum NEFA. In conclusion, prepartum fat supplementation decreased leptin concentration prepartum.
