Effects of secondary compounds from cactus and acacias trees on rumen microbial profile changes performed by Real-Time PCR

Plant rich secondary compounds had antimicrobial effects by acting against different rumen microbial populations. The current study investigated the influence of spineless cactus (Opuntia ficus indica f. inermis), Acacia nilotica and A. saligna on rumen microbial fermentation, using in vitro gas production technique, and microbial population profile changes, using a molecular-based technique (Real-Time PCR). The acacias and Opuntia reduced significantly total gas production (p<0.01), rumen CH4 production (p?0.01) and ammonia concentration (p<0.001). At 24h of incubation, Fungi population was 0.30- and 0.03 -fold reduced with A.nilotica and Opuntia as compared to 0h, but 2-and 1.24- fold higher with A.cyanophylla .Increases in the abundance of F.succinogenes were observed in all substrates; however, the tanniferous plants and Opuntia reduced the relative abundance of R.flavefaciens. Methanogenic population was increased with all substrates, except for Opuntia (0. 90- fold lower than the control). There was a significant reduction (p<0.05) in rumen protozoa count with A.cyanophylla, Opuntia and A.nilotica (3.68; 5.59 and 5.34 times, respectively). Results suggested that tannin sources from A.nilotica and A.cyanophylla had an indirect effect on methanogenesis. This study showed an antimicrobial activity of oxalates content of O. ficus indica

Data for a meta-analysis of the adaptive layer in adaptive large neighborhood search.

Meta-analysis, a systematic statistical examination that combines the results of several independent studies, has the potential of obtaining problem- and implementation-independent knowledge and understanding of metaheuristic algorithms, but has not yet been applied in the domain of operations research. To illustrate the procedure, we carried out a meta-analysis of the adaptive layer in adaptive large neighborhood search (ALNS). Although ALNS has been widely used to solve a broad range of problems, it has not yet been established whether or not adaptiveness actually contributes to the performance of an ALNS algorithm. A total of 134 studies were identified through Google Scholar or personal e-mail correspondence with researchers in the domain, 63 of which fit a set of predefined eligibility criteria. The results for 25 different implementations of ALNS solving a variety of problems were collected and analyzed using a random effects model. This dataset contains a detailed comparison of ALNS with the non-adaptive variant per study and per instance, together with the meta-analysis summary results. The data enable to replicate the analysis, to evaluate the algorithms using other metrics, to revisit the importance of ALNS adaptive layer if results from more studies become available, or to simply consult the ready-to-use formulas in the summary file to carry out a meta-analysis of any research question. The individual studies, the meta-analysis and its results are described and interpreted in detail in Renata Turkeš, Kenneth Sörensen, Lars Magnus Hvattum, Meta-analysis of Metaheuristics: Quantifying the Effect of Adaptiveness in Adaptive Large Neighborhood Search, in the European Journal of Operational Research

Significant benefits of AIP testing and clinical screening in familial isolated and young-onset pituitary tumors

Context Germline mutations in the aryl hydrocarbon receptor-interacting protein (AIP) gene are responsible for a subset of familial isolated pituitary adenoma (FIPA) cases and sporadic pituitary neuroendocrine tumors (PitNETs). Objective To compare prospectively diagnosed AIP mutation-positive (AIPmut) PitNET patients with clinically presenting patients and to compare the clinical characteristics of AIPmut and AIPneg PitNET patients. Design 12-year prospective, observational study. Participants & Setting We studied probands and family members of FIPA kindreds and sporadic patients with disease onset ≤18 years or macroadenomas with onset ≤30 years (n = 1477). This was a collaborative study conducted at referral centers for pituitary diseases. Interventions & Outcome AIP testing and clinical screening for pituitary disease. Comparison of characteristics of prospectively diagnosed (n = 22) vs clinically presenting AIPmut PitNET patients (n = 145), and AIPmut (n = 167) vs AIPneg PitNET patients (n = 1310). Results Prospectively diagnosed AIPmut PitNET patients had smaller lesions with less suprasellar extension or cavernous sinus invasion and required fewer treatments with fewer operations and no radiotherapy compared with clinically presenting cases; there were fewer cases with active disease and hypopituitarism at last follow-up. When comparing AIPmut and AIPneg cases, AIPmut patients were more often males, younger, more often had GH excess, pituitary apoplexy, suprasellar extension, and more patients required multimodal therapy, including radiotherapy. AIPmut patients (n = 136) with GH excess were taller than AIPneg counterparts (n = 650). Conclusions Prospectively diagnosed AIPmut patients show better outcomes than clinically presenting cases, demonstrating the benefits of genetic and clinical screening. AIP-related pituitary disease has a wide spectrum ranging from aggressively growing lesions to stable or indolent disease course

Severe gynecomastia due to anti androgens intake: A case report and literature review

Gynecomastia is the most bothersome side effect in men taking antiandrogens. It is exceptionally severe and distressing physically and mentally as in the reported case. A man, aged 63, with a history of a well-treated macroprolactinoma, was referred in 2004 for gynecomastia that appeared after treatment by microsurgery, radiotherapy and flutamide for a lesion suspected to be prostate cancer. Clinical examination was normal except for huge enlargement of the breasts. Mammography and breasts MRI did not show any tumor. There was not any metastasis of the supposed prostate cancer and prostatic acid phosphates were within normal ranges. Hormonal exploration showed subclinical hypogonadism [testosterone: 7.4 ng/ml (n: 3-9), FSH: 14.9 mu/ml (n: 0.7-11) and LH: 9.7 mu/ml (n: 0.8-7.6)]. Testes ultrasounds were normal. Radiological and hormonal adrenal explorations were normal [Cortisol: 76 ng/ml (n: 50-250), DHEA-S: 59 μg/ml (n: 50-560), E2:40.2 pg/ml (n < 50)]. Body scan was normal too. The discussed etiologies were post radiation subclinical hypogonadism, and treatment with anti androgens. After flutamide withdraw, there was not any sign of prostate cancer recurrence, and gynecomastia decreased significantly, but did not disappear probably because of fibrosis
