Further Clinical Delineation of Prolidase Deficiency Associated with c.1103T>G Variant.

Introduction: Prolidase deficiency is a rare multisystemic disease associated with collagen metabolism. Clinical manifestations and age of onset are highly variable. Prolidase deficiency is caused by homozygous variants in the gene.

Potent carbonic anhydrase I, II, IX and XII inhibition activity of novel primary benzenesulfonamides incorporating bis-ureido moieties.

A novel series of twelve aromatic bis-ureido-substituted benzenesulfonamides was synthesised by conjugation of aromatic aminobenzenesulfonamides with aromatic bis-isocyanates. The obtained bis-ureido-substituted derivatives were tested against four selected human carbonic anhydrase isoforms (hCA I, hCA II, hCA IX and hCA XII). Most of the new compounds showed an effective inhibitory profile against isoforms hCA IX and hCA XII, also having some selectivity with respect to hCA I and hCA II.

Adaptive group testing in a compartmental model of COVID-19.

Various measures have been implemented around the world to prevent the spread of SARS-CoV-2. A potential tool to reduce disease transmission is regular mass testing of a high percentage of the population, possibly with pooling (testing a compound of several samples with one single test). We develop a compartmental model to study the applicability of this method and compare different pooling strategies: regular and Dorfman pooling.

Early Phase of the COVID-19 Outbreak in Hungary and Post-Lockdown Scenarios.

COVID-19 epidemic has been suppressed in Hungary due to timely non-pharmaceutical interventions, prompting a considerable reduction in the number of contacts and transmission of the virus. This strategy was effective in preventing epidemic growth and reducing the incidence of COVID-19 to low levels. In this report, we present the first epidemiological and statistical analysis of the early phase of the COVID-19 outbreak in Hungary.

Risk Assessment of Novel Coronavirus COVID-19 Outbreaks Outside China.

We developed a computational tool to assess the risks of novel coronavirus outbreaks outside of China. We estimate the dependence of the risk of a major outbreak in a country from imported cases on key parameters such as: (i) the evolution of the cumulative number of cases in mainland China outside the closed areas; (ii) the connectivity of the destination country with China, including baseline travel frequencies, the effect of travel restrictions, and the efficacy of entry screening at destination; and (iii) the efficacy of control measures in the destination country (expressed by the local reproduction number R loc ). We found that in countries with low connectivity to China but with relatively high R loc , the most beneficial control measure to reduce the risk of outbreaks is a further reduction in their importation number either by entry screening or travel restrictions.

Impact of weather seasonality and sexual transmission on the spread of Zika fever.

We establish a compartmental model to study the transmission of Zika virus disease including spread through sexual contacts and the role of asymptomatic carriers. To incorporate the impact of the seasonality of weather on the spread of Zika, we apply a nonautonomous model with time-dependent mosquito birth rate and biting rate, which allows us to explain the differing outcome of the epidemic in different countries of South America: using Latin Hypercube Sampling for fitting, we were able to reproduce the different outcomes of the disease in various countries. Sensitivity analysis shows that, although the most important factors in Zika transmission are the birth rate of mosquitoes and the transmission rate from mosquitoes to humans, spread through sexual contacts also highly contributes to the transmission of Zika virus: our study suggests that the practice of safe sex among those who have possibly contracted the disease, can significantly reduce the number of Zika cases.

Gallstone ileus as an unexpected complication of cholelithiasis: diagnostic difficulties and treatment.

Background: Gallstone ileus is a rare complication of cholelithiasis, mostly in the elderly. The aim of this study was to evaluate our experience with 12 gallstone ileus cases and discuss current opinion as reported in the literature.

Methods: Data of 12 patients operated between January 1998 and January 2008 with gallstone ileus were retrospectively studied.

The relationship among vitamin C, beta-carotene, vitamin A, progesterone and oestradiol 17-beta concentrations in plasma and cyst fluid of Holstein cows with ovarian cyst.

The aims of this study were to determine the concentrations of the progesterone, oestradiol-17-beta, vitamin A, C and beta-carotene in plasma and cyst fluid and to relate these values with cystic diameter and membrane thickness of Holstein cattle with ovarian luteal cyst. 1650 Holstein cows were examined for the presence of the ovarian cyst and luteal and follicular cystic ovaries were obtained following slaughtering in personal slaughterhouse in Konya-Turkey. 15 Luteal and 15 follicular cystic ovaries were distinguished by rectal palpation and by post mortem ultrasonographic examination.

Effect of the administration of flunixin meglumine on pregnancy rates in Holstein heifers.

Fifty-two 15-month-old Holstein heifers were synchronised with single or double injections of prostaglandin F(2alpha), followed by an injection of gonadotrophin-releasing hormone (gnrh) 48 hours later, and inseminated 12 to 14 hours after the injection of gnrh (day 0). Half of them were then injected twice intramuscularly with 1.1 mg/kg flunixin meglumine 12 hours apart, on the evening of day 15 and the morning of day 16, and the other 26 were not treated.

Effect of seasonal conditions on oestrus occurrence and postpartum period in Anatolian water buffaloes.

Oestrus and calving records of Anatolian buffaloes were analyzed to investigate influence of climatic conditions on oestrus occurrence and postpartum period. Oestrus records showed a seasonal pattern concentrated between July and September which is the warmest period of the year. Likewise, more than half (52.

Testosterone secretion and semen plasma enzyme activity in rams with genital pathology stimulated with GnRH.

Testosterone secretion in response to GnRH stimulation and enzymatic activity of semen plasma was evaluated comparatively in rams with or without genital abnormality. Scrota, testes and epididymides of 128 rams between 1.5 and 6 years old from various breeds were examined clinically and ultrasonographically.

Influence of sugar supplementation of the extender on motility, viability and acrosomal integrity of dog spermatozoa during freezing.

Influence of different sugars supplemented to the extender on the motility, viability and intact acrosome rates of dog spermatozoa during dilution, equilibration and freezing was studied. The ejaculate was divided into 10 aliquots, which were diluted 1:3 with TRIS-citric acid extender containing 240 mMTRIS, 63 mM citric acid, 8% (v/v) glycerol, 20% (v/v) egg yolk and 70 mM sugar, which was either fructose, galactose, glucose, xylose (monosaccharide), lactose, trehalose, maltose, sucrose (disaccharide) or raffinose (trisaccharide). No sugar was added to the extender in the control group.

Spermatic granuloma in the ram: diagnosis by ultrasonography and semen characteristics.

Ultrasonographic appearance of the testis and epididymis, and seminal characteristics, with regard to localization of spermatic granuloma were studied. In rams with spermatic granuloma (n = 9), diagnosed by clinical or ultrasonographic examinations before histopathological confirmation, localization of each lesion was recorded. Epididymal granulomas, caput and cauda, were seen as anechoic or hyperechoic areas with a distinct margin with or without a hyperechoic capsule.

Twenty-one maiden and 29 pluriparous milking Ankara Saanen goats received either two i.m. injections of PGF(2)alpha (n=25) or intravaginal MAP sponges (n=25) early in November at the start of the breeding season.
