MHT-X: Netiešsaistes Vairāku Hipotēžu Izsekošana, optimizēta ar Algoritmu X

2021

Ātrdarbīga un plaši pielietojama netiešsaistes vairāku hipotēžu izsekošanas imple- mentācija optimizēta ar Algoritmu X ir izveidota izmantojot Python. Programma- tūra ir paredzēta zinātniskiem nolūkiem, kam nav nepieciešama tiešsaistes apstrāde. Tiek izmantota orientēta grafa arhitektūra un ar vairākiem piegājieniem ar progre- sīvi lielāku laika logu tiek veikta šķautņu veidošana maksimizējot trajektoriju var- būtību. Esošajā stadijā implementācija tika veidota, lai tiktu pielietota daudzfāzu hidrodinamisko plūsmu analīzei, tā ir spējīga rekonstruēt objektu kustību, šķelša- nos un saplūšanu. Iespējamās objektu asociācijas un trajektoriju grafa šķautņu varbūtības tiek noteiktas izmantoju vāj…

Body mass index and impact on semen quality of men attending an infertility clinic

2019

Background: The reproductive consequences of lifestyle factors in men are still controversial. In this prospective study, we verified the impact of body mass index alterations on semen parameters of patients who attended an infertility clinic. Materials and Methods: Semen samples from 156 subjects aged 22 to 53 years were analyzed. Smokers were categorized as mild (≤ 10 cigarettes/day), moderate (10-20 cigarettes/day”) and heavy smokers (> 20 cigarettes/day”). Men were grouped based upon calculated body mass index values (underweight, <18.5 Kg/m2; normal, 18.5-24.9 Kg/m2; overweight, 25-29.9 Kg/m2; obese, ≥ 30 Kg/m2). The data collected included patient height and weight, semen volume…

Preconception genome medicine: current state and future perspectives to improve infertility diagnosis and reproductive and health outcomes based on i…

2021

Abstract BACKGROUND Our genetic code is now readable, writable and hackable. The recent escalation of genome-wide sequencing (GS) applications in population diagnostics will not only enable the assessment of risks of transmitting well-defined monogenic disorders at preconceptional stages (i.e. carrier screening), but also facilitate identification of multifactorial genetic predispositions to sub-lethal pathologies, including those affecting reproductive fitness. Through GS, the acquisition and curation of reproductive-related findings will warrant the expansion of genetic assessment to new areas of genomic prediction of reproductive phenotypes, pharmacogenomics and molecular embryology, fur…

Failures (with some successes) of assisted reproduction and gamete donation programs

2013

Although the possibilities for the treatment of infertility have been improved tremendously, not every couple will be treated successfully.Crude overall pregnancy rates of 50-65% per patient can be achieved nowadays, irrespective of the type of profertility treatment applied first.IVF only accounts for about 20% of the pregnancies achieved. Dropout is an important reason for not reaching the estimated pregnancy rate. Even after failed IVF, spontaneous pregnancies do occur. Sperm and oocyte donation (OD) offer additional chances to subfertile couples. Severity of the male factor (in sperm donation) and young donor age (in OD) are important determinants of success.Analysis of assisted reprodu…

Male infertility: an obstacle to sexuality?

2016

International audience; Interactions between infertility and sexuality are numerous and complex. Infertile men may suffer from sexual dysfunction (SD) when undergoing an assisted reproductive technology programme. We undertook a review both in French and English of the available data on male SD when being diagnosed with a fertility problem with a specific focus on azoospermic men. The review was performed over a 30-year time period using PubMed/Medline. The sexual concerns and needs of infertile/sterile men for whom potential parenting can be compromised were evaluated. When diagnosed with infertility, men usually go through a crisis that can have a deleterious effect on their sexuality wit…

Penicillium lanoso-viride AMP dezamināzes attīrīšanas preparatīvo metožu izstrāde

2015

AMP dezamināze ir glikoproteīns, kam piemīt imūnmodulējošas īpašības, tādēļ darba mērķis bija izstrādāt efektīvu un ātru AMPD attīrīšanas metodi no Penicillium lanoso–viride 8D, ar kuras palīdzību būtu iespējams iegūt proteīna preparātu ar pietiekami augstu AMPD aktivitāti. Izmantojot divfāžu frakcionēšanu ar PEG un amonija sulfātu, kam seko proteīnu precipitācija ar acetonu, tika atdalīts pigments un iegūts ekstrakts ar līdzīgu AMPD specifisko aktivitāti un lielāku aktivitātes iznākumu, kāds tiek iegūts, izmantojot proteīnu precipitāciju ar amonija sulfātu – līdz šim izmantoto metodi. AMPD attīrīšanai no koncentrētiem ekstraktiem tika izmantoti DEAE–Sephadex A–25, fosfoceluloze un konkanav…

Impact of FIGO type 3 uterine fibroids on in vitro fertilization outcomes: A systematic review and meta‐analysis

2023

Background: The effect of FIGO (the International Federation of Gynecology & Obstetrics) type 3 myomas on in vitro fertilization (IVF) is uncertain. Objectives: To evaluate whether FIGO type 3 myomas affect IVF outcomes, through a systematic review and meta-analysis (CRD42022379700). Search strategy: Electronic databases were searched until November 15, 2022. Selection criteria: Studies evaluating the effects of FIGO type 3 myomas on IVF outcome. Data collection and analysis: Pooled results were expressed as odds ratios (OR) with 95% confidence intervals (CI). Heterogeneity was assessed using Higgins I2 . Sources of heterogeneity were explored with sensitivity and subgroup analyses. Mai…

Organisko materiālu trešās kārtas dielektriskās uzņēmības noteikšana ar "z-scan" metodi

2016

Darba gaitā tika pētīti organiskā savienojuma DMABI dažādu atvasinājumu divfotonu absorbcijas (DFA) un Kerra efekti, lai iegūtu informāciju, kā dažādas funkcionālās grupas ietekmē iepriekš minētos nelineāri optiskos (NLO) efektus. Plašāka informācija par saistībām starp molekulu uzbūvi un to NLO efektiem ļaus veidot atbilstošākus organiskos materiālus dažādām iekārtām optiskā starojuma jaudas kontrolēšanai, optisko datu ierakstīšanai un apstrādei. Šādu iekārtu izveide ir būtiska optisko datoru veidošanai. Materiālu pētīšanai tika izveidota eksperimentālā iekārta pēc “z-scan” metodes principiem. Eksperimentālie mērījumi tika veikti izmantojot lāzerus ar nanoskeunžu un pikosekunžu gariem impu…

Divfāzu plūsmas modeļeksperimenti metalurģijas procesu hidrodinamikas izpētei

2019

Šajā darbā tiek apskatītas ūdens – gāzes plūsmas modeļeksperimenti. Pēc divfāzu plūsmu un dažādu vielu plūsmu līdzību iepazīšanas, tiek veikta ūdens modeļeksperimentu izveide. Dažādu eksperimentu izveide ļauj iegūt kvantitatīvus datus un parametrus par plūsmu īpašībām. Dati tiek apstrādāti un iegūti plūsmas raksturīgie lielumi un bezdimensionāli skaitļi. Šīs vērtības tiek salīdzinātas ar industrijā pielietotiem risinājumiem un pielietojumiem divfāzu plūsmām.
