Molecular Phylogenetic Analysis of Caridina weberi Species Group around Japan, with the First Record of Caridina tupaia de Mazancourt, Marquet & Keith, 2019 (Crustacea: Decapoda: Atyidae) from Japan
Authors: Nagai Hiroto , Kitano Tadashi , Imai Hideyuki 
Published: May 2023

Recently, numerous new species of Caridina weberi species group were described from around Polynesia. This study reports the molecular phylogenetic data of the Japanese specimens belonging to C. weberi species group based on the mitochondrial 16S rRNA and cytochrome c oxidase subunit I gene. The results suggested that C. laoagensis Blanco, 1939, C. macrodentata Cai & Shokita, 2006, C. multidentata Stimpson, 1860, C. prashadi Tiwari & Pillai, 1971 and C. tupaia de Mazancourt, Marquet & Keith, 2019 are distributed in Japan. This is the first record of C. tupaia on Ishigaki-jima Island, Ryukyu Archipelago, southern Japan and the northernmost record of this shrimp. Attempted to find C. okinawa, belonging to C. weberi species group, for the first time in about 50 years, but there were no Atyid shrimps in its type locality. Based on the data of mitochondrial DNA fragments, we suggest that if the divergence estimate in C. weberi species group exceed 3% for 16S rRNA, it may be an interspecific variation. We also reveal the existence of two unnamed species which had been identified as C. macrodentata and C. multidentata. Caridina multidentata is known to be distributed in Japan (type locality), Taiwan, Fiji and Madagascar, however East Asian and Malagasy samples were shown to be distinct species, their divergence estimates were more than 10% for 16S rRNA. We also provide the key to the Japanese species of C. weberi species group.

Abstract

OBJECTIVE
To establish normal values for pre- and post-prandial bile acids and protein C in Pacific harbor seal (Phoca vitulina richardsi) pups.

ANIMALS
45 harbor seals undergoing rehabilitation at the Vancouver Aquarium Marine Mammal Rescue Centre, 0 to 16 weeks, and deemed healthy aside from malnutrition or maternal separation.

PROCEDURES
Venous blood was collected from the intervertebral extradural sinus in fasted seals and again 2 hours after a fish meal.

RESULTS
The reference interval (90% CL, confidence limit) for pre-prandial (fasting) bile acids was 17.2 μmol/L to 25.4 μmol/L, post-prandial bile acids were 36.9 μmol/L to 46.4 μmol/L, and protein C was 72.3% to 85.4%, across ages. For comparison between developmental ages, pups were grouped into 3 age classes: < 14 days, 5 to 8 weeks, and 10 to 16 weeks. Age affected pre- and post-prandial bile acids; pups < 14 days had significantly higher pre-prandial bile acids (36.0 μmol/L ± 16.5 μmol/L; P < .0001) than other age groups and pups 5 to 8 weeks had significantly higher post-prandial bile acids (50.4 μmol/L ± 21.9 μmol/L; P < .001). Protein C was also affected by age, with seals < 14 days having significantly lower values (mean, 51.8% ± 16.7%; P < .0001).

CLINICAL RELEVANCE
This study established normal reference intervals for bile acids in harbor seal pups and offered a preliminary investigation into protein C in pinnipeds. The bile acid values from 0- to 16-week-old seal pups were well above established normal ranges for domestic species, highlighting the utility of age- and species-specific reference ranges. The values presented here and the differences across age classes will aid clinicians in accurately diagnosing hepatobiliary disease in harbor seal pups.
Prevalence of Hepatitis B in Random Bulgarian Blood Samples – A Single-Site Experience
Authors: Gotseva A. , Naseva E. 
Published: May 2023

Abstract
The worldwide distribution of the HBV infection has usually been estimated by the prevalence of hepatitis B surface antigen (HBsAg) among the general population. Total antibodies for hepatitis B core antigen (anti-HBc) are the most important diagnostic marker for proving prior exposure to HBV.

Aim
The aim of this study was to determine the prevalence of Hepatitis B virus (HBV) infection among Bulgarian population. Reliable epidemiologic data is needed to estimate the prevalence of Hepatitis B in order to determine the actual burden of the infection and to plan prevention and control measures.

Materials and methods
A total of 2140 serum samples were tested for major serological markers of HBV (HBsAg and anti-HBc) for a period of two years (2018-2019).

Results
We established an intermediate prevalence of HBsAg (5.1%) and high prevalence of anti-HBc (27%) among HBsAg negative individuals.

Conclusion
In conclusion, the prevalence of Hepatitis B is much higher among those born before the introduction of universal hepatitis B vaccination in Bulgaria (1992).

Abstract
The most common primary cardiac tumors are myxomas, while cardiac hamartomas are rare. Cardiac hamartomas may constitute manifestation of a genetic disorder such as tuberous sclerosis, or could be diagnosed independently as a solitary lesion. We present two rare cases of primary cardiac tumors detected via diagnostic imaging and subsequent histopathology examination. The first described case is that of a male preterm foetus with multiple rhabdomyomas in the heart, discovered during foetal echocardiography. The finding was later confirmed by autopsy, which also revealed presence of cortical tubers with typical balloon cells constituting well known epileptogenic lesions in the foetal brain. The second case describes an even rarer benign cardiac lesion – a hamartoma of mature cardiomyocytes – which was discovered by chance in a 49-year old female patient during echocardiography. The performed CT scan revealed a 37 x 16 x 12 mm tumor in the right atrium obstructing the superior vena cava inlet. The malformation was surgically removed and examined histologically revealing disorganized hypertrophic mature cardiomyocytes, partly separated by fibrous strands and admixed with mature adipocytes. Differential diagnosis was performed to rule out other benign tumors with myocyte differentiation – cardiac rhabdomyoma, histiocytoid cardiomyopathy and adult cellular rhabdomyoma.

Conclusion
The diagnosis of cardiac hamartomas was possible only after pathomorphological examination of material from the tumors. Reporting of rare neoplasms is crucial in order to determine their prevalence and to inform clinical practice.

Abstract
The current study assessed the benefits of marjoram essential oil (MEO) in reducing the aflatoxin B1 (AFB1) toxicity in growing rabbits. Forty-eight rabbits, aged 4 weeks, were randomly assigned to four groups (4 replications of 3 rabbits/replicate) as follows: BD group (control); AFB1 group (supplemented with AFB1 0.3 mg/kg diet); MEO-supplemented group (1 g MEO/kg diet); AFB1 + MEO group (AFB1 0.3 mg/kg diet + 1 g MEO/kg diet). AFB1 exposure resulted in reduction of rabbit growth and total protein and albumin content in serum; increased liver function related enzymes (ALP, ALT and AST); induced oxidative stress displayed by lower level of antioxidant enzymes (CAT and GSH), increased biomarkers of DNA and lipid oxidative damage with significant upregulation of the tumor suppressor protein interferon-γ, interleukin 1β, tumor necrosis factor-α and heat shock protein-70 when compared to the control (P<0.05). Moreover, exposure to AFB1 increased the bioaccumulation of AFB1 residues in rabbit liver. Supplementation of MEO in the AFB1-exposed rabbits alleviated all of its negative effects. In conclusion, dietary addition of 1 g MEO could effectively ameliorate the adverse impacts of AFB1 on rabbit growth; enhanced their antioxidants and reduced oxidative stress and inflammatory response indicators, as well as the AFB1 residues in liver.

Abstract
Hypertrophic pyloric stenosis (HPS) is a gastrointestinal condition that affects newborns and young infants and is characterized by progressive, non-bilious projectile vomiting. This study aimed to investigate the demographics and clinical manifestations of HPS. A retrospective, non-randomized study was conducted over a period of three years (2019-2022) and included 29 patients diagnosed with HPS at the Pediatric Clinic of the County Clinical Emergency Hospital of Constanta. The results showed a significant male predilection, with a ratio of 1:4.8, and a seasonal variation with a higher incidence of HPS in the summer months. The primary symptom of HPS was non-bilious forceful vomiting after feeding, observed in nearly all cases. Other symptoms included dehydration, stagnation and decrease in weight. The thickness of the pyloric muscle was measured using ultrasonography and was found to be an average of 54.5 mm, with a range between 30 mm and 79 mm, which is considered a strong indication of HPS. This study highlights the importance of considering HPS as a possible diagnosis in newborns and young infants presenting with symptoms of projectile vomiting, and emphasizes the need for further research into the seasonal variation of HPS and its underlying causes.

Abstract
Rankine's theory stated that the soil failure plane behind the monolith retaining wall is a linear equation and is applied similarly to the plane of precast block retaining walls. However, the actual failure plane in the field may differ from the theory. This research is done to determine the plane of soil failure behind a precast block retaining wall using wall modeling tests in the laboratory. Several stages for laboratory tests are carried out. Starting with making a precast block retaining wall with the planned dimensions, then a failure test is carried out by giving variations and adding loads in stages. The plane and pattern of failure from recorded laboratory tests. The failure shape is analyzed to obtain the mathematical equation. The shape of the failure obtained from the analysis is in the form of an S curve, with a power three polynomial function. Furthermore, the total area of the failure land is calculated. When compared with the results of the analysis using Rankine's theory equation, it is found that the area of the failure soil from the laboratory test of the precast block retaining wall is smaller, while the length of the failure of the soil is longer. The altitude simulation is continued based on the obtained mathematical model.

Published: May 2023

Abstract
The main problem is to raise the standard of construction, rethinking concrete's expanding potential as a construction material. The scarcity of river sand as a fine aggregate ingredient is currently a widespread issue for many concrete plants. As a result, quarried stones that were accessible locally were used as fine aggregate. Crushed Rock Particles, also known as crushed sand, performs better in terms of fresh characteristics since there are more fines present in CRF than in river sand. The current study additionally examines the relationship between plastic viscosity and the fresh and hardened SCC properties. As a partial substitute for Ordinary Portland Cement, Fly Ash and Ground Granulated Blast Slag blends are used to generate binary and ternary. The experimental tests satisfactorily validate the suggested blend design. The results shown that SCC mixture with ternary blend, binary blend with GGBS, fly ash, and blend with pure OPC are suitable for creating fresh characteristics. Additionally, it was found that a cohesive and workable mix was produced when 100 % CRF was used in place of sand.
