The present study was conducted to reveal characteristic features of albino large rabbit (JW-AKT) which we formerly established a specific pathogen-free (SPF) colony. Body weights of JW-AKT rabbit at 52 weeks old was 5.7 ± 0.4 kg in males and 6.4 ± 0.4 kg in females. Weight of body, heart, lung and kidney in JW-AKT rabbit was significantly higher than in Japanese white and New Zealand white rabbits in both sexes. Though the body weight (BW) was rather lower in males, body length and brain weights tended to be higher in males than in females. Since body fat was significantly higher in females, what affects difference in BW is body fat, rather than the physical constitution of female JW-AKT rabbit. No critical sex difference was found in hematological parameters in JW-AKT rabbit. The results indicated that JW-AKT were about 1.5 times larger than the general laboratory rabbits with common properties in hematology. Thus, JW-AKT rabbit could be used as a novel SPF experimental animal model with some advantages in surgical experiments or collection of large amount of biological specimen. [ABSTRACT FROM AUTHOR]

Abstract: Purpose: Anterior chamber depth (ACD) is an important preoperative parameter in anterior segment surgery. Several factors are known to influence ACD, including race and geography. Our purpose was to sample data from various countries to characterize differences in ACD worldwide and, if any, assess their level of clinical significance. Setting: International, multicenter. Methods: Cross-sectional study. Using the Pentacam Eye Scanner (OCULUS GmbH, Wetzlar, Germany), we analyzed ACD measurements from 1077 eyes of 568 normal adults from nine countries spanning six continents. Differences between countries were assessed by comparison of 95% confidence intervals and by ANOVA. Normative thresholds were constructed at three standard deviations (SD) above and below the mean. Results: Mean ACD was 3.11mm overall, ranging from 2.91mm (New Zealand) to 3.24mm (United States). The ACD among New Zealanders was significantly shallower (P <.0001) than that among Chinese, Egyptians, Germans, Indians, and Americans. The maximum difference in the mean ACDs was 0.33mm, between New Zealand and the United States. The shallowest 0.15% of normal ACD values occurred below 2.04mm overall, ranging from 1.69mm (New Zealand) to 2.42mm (United States). The deepest 0.15% of normal ACD values occurred above 4.18mm overall, ranging from 4.03mm (Saudi Arabia) to 4.35mm (Brazil). Conclusions: ACD did not vary significantly in the countries studied, with the notable exception of New Zealand. Surgeons should anticipate a greater likelihood of a shallow ACD when evaluating patients from New Zealand. Clinical examination and direct measurement of ACD are recommended. Finally, deep ACD has limited clinical utility in screening for keratoconus. [Copyright &y& Elsevier]

The complete mitochondrial genome of the yellow coloured honeybee
Apis mellifera from North Island, New Zealand was analyzed using next-generation sequencing. The mitochondrial genome was a 16,349bp circular molecule and was predicted to contain 13 protein-coding genes (PCGs), 22 tRNA genes and two rRNA genes. The initiation codon ATA was found in two genes, ATG in four genes, ATT in six genes, and ATC in one gene, while the termination codon TAA was observed in all the PCGs. Phylogenetic analysis using the sequence of 23 closely related taxa suggested a sister relationship with the Italian strainA. mellifera ligustica . [ABSTRACT FROM AUTHOR]- Published

SODIUM bicarbonate , *ACIDOSIS , *CLINICAL trials - Abstract
OBJECTIVES: To identify the best population, design of the intervention, and to assess between-group biochemical separation, in preparation for a future phase III trial. DESIGN: Investigator-initiated, parallel-group, pilot randomized double-blind trial. SETTING: Eight ICUs in Australia, New Zealand, and Japan, with participants recruited from April 2021 to August 2022. PATIENTS: Thirty patients greater than or equal to 18 years, within 48 hours of admission to the ICU, receiving a vasopressor, and with metabolic acidosis (pH < 7.30, base excess [BE] < -4 mEq/L, and Paco2 < 45 mm Hg). INTERVENTIONS: Sodium bicarbonate or placebo (5% dextrose). MEASUREMENTS AND MAIN RESULT: The primary feasibility aim was to assess eligibility, recruitment rate, protocol compliance, and acid-base group separation. The primary clinical outcome was the number of hours alive and free of vasopressors on day 7. The recruitment rate and the enrollment-to-screening ratio were 1.9 patients per month and 0.13 patients, respectively. Time until BE correction (median difference, -45.86 [95% CI, -63.11 to -28.61] hr; p < 0.001) and pH correction (median difference, -10.69 [95% CI, -19.16 to -2.22] hr; p = 0.020) were shorter in the sodium bicarbonate group, and mean bicarbonate levels in the first 24 hours were higher (median difference, 6.50 [95% CI, 4.18 to 8.82] mmol/L; p < 0.001). Seven days after randomization, patients in the sodium bicarbonate and placebo group had a median of 132.2 (85.6-139.1) and 97.1 (69.3-132.4) hours alive and free of vasopressor, respectively (median difference, 35.07 [95% CI, -9.14 to 79.28]; p = 0.131). Recurrence of metabolic acidosis in the first 7 days of follow-up was lower in the sodium bicarbonate group (3 [20.0%] vs. 15 [100.0%]; p < 0.001). No adverse events were reported. CONCLUSIONS: The findings confirm the feasibility of a larger phase III sodium bicarbonate trial; eligibility criteria may require modification to facilitate recruitment. [ABSTRACT FROM AUTHOR]

- Abstract
Perinatal mortality was estimated by the regression equation log10 Y = 0.7826log10X + 0.08, obtained by perinatal mortality (Y) and maternal mortality (X) in Japan in 1960-1990. The error rate was approximately 9% in the estimation. Unpublished Japanese perinatal mortality in 1899-1947 was estimated from maternal mortality by using the equation, and appropriate results were obtained. Perinatal mortalities of the world's countries were estimated from their maternal mortalities listed in UNICEF reports with use of the above equation. Two peaks were noted in the country number distribution at 0-19 and 120-140 of estimated perinatal mortality. The mortality was 20-99 in 43% of 111 countries analyzed and 100 or more in 25%. The results suggest that further efforts should be made for the improvement of worldwide maternal and child health.
