Generation of an Inducible Avp Knockout Mouse Line Using CRISPR/Cas9 and Cre/LoxP

Background: Arginine vasopressin (AVP) is a peptide hormone coded by the Avp gene, synthesized in the hypothalamus and secreted by the posterior pituitary. Dysregulation of AVP secretion contributes to a variety of human diseases. Previous studies of functional roles of AVP have been largely dependent on the use of Brattleboro rats, which manifest a spontaneous mutation in the Avp gene and lack circulating AVP. Despite their utility, Brattleboro rats are diffcult to breed owing largely to the fixed nature of the Avp mutation, resulting in increased neonatal death and behavioral effects in the adults. Consequently, commercial breeders have ceased production, despite a continued need. To fill this need, we have now created a mouse model with a tamoxifen-inducible deletion of AVP. Methods: We employed CRISPR/Cas9 to target the desired regions (first intron and 3' downstream) within the Avp gene. Successful insertion of the two loxP sites was confirmed by PCR using primers flanking the targeted regions. Restriction enzymes BamHI or EcoRI were used to confirm correct targeting. For additional confirmation, PCR products were cloned into the TA-cloning vector and sequenced. Mice harboring the floxed allele were mated to B6.Cg-Tg(CAG-cre/Esr1*)5Amc/J mice that globally express a tamoxifen-inducible Cre recombinase. Results: The resultant homozygous conditional knockout mice ( Cre+ Avpflx/ flx) are viable, fertile, and show no signs of polydipsia or polyuria prior to induction, indicating that the conditional alleles retain their wild-type function. Induction of Cre-mediated recombination by administration of tamoxifen (2-3 mg q.d., i.p. for 5 days) in 8-week-old mice resulted in a decrease in urine osmolality from 2076±138 to 122±6 mOsm/kgH2O on day 31 after induction (p<0.0001). Sanger sequencing demonstrated the expected 1245 bp deletion at the Avp locus. The kidney parenchyma was structurally normal with no evidence of medullary atrophy 6 weeks after induction. Immunoblotting of AQP2 in the inner medulla showed a significant decrease in AQP2 band density in Cre+ Avpflx/ flx mice to 27±14 % of values in Cre− floxed control mice (p<0.05). Conclusion: We developed an inducible AVP knockout mouse line ( Cre+ Avpflx/ flx) that will be shared with the research community and are likely to be useful for further study of regulation of water balance and polycystic kidney disease, as well as neural, vascular, and metabolic roles of vasopressin.

Preface

The 9th Light Symposium, December 4-6, 2023 · Stockholm, Sweden Light Symposium 2023: Architecture Lighting Environments - Space With(Out) Light Daylight and electric light are an integral part of our built environment, and the sustainable design of lighting in this context, its presence, absence, and variability over time, requires research and practice that is both trans- and interdisciplinary.Although the presence of light is intimately linked to the life of humans, flora, and fauna, research and practice have not yet fully explored how light and dark can shape the built environment in a sustainable and holistic way.Research and practice into the affects and effects of light combine lighting design with other fields, including, for example, architecture, engineering, computer science, visualization, arts, humanities, social sciences, environmental psychology, health sciences, cognitive sciences, and more. The Light Symposium is an annual, international event to facilitate discussions and the exchanging of ideas; currently, it is coordinated by four academic partners; the Lighting Design Division at KTH in Sweden, Hochschule Wismar in Germany, AAU Copenhagen in Denmark, and SNU Kongsberg in Norway.The 9th Light Symposium, LS2023, was held in Stockholm from the 4th-6th of December 2023; it was hosted by the Architectural Lighting Design Division of KTH Royal Institute of Technology, in collaboration with the Perception Studio of Konstfack, the University of Arts, Crafts, and Design. During the 2,5 days of the symposium, more than 200 participants came together to share and learn about current research and design across different fields within architectural and urban lighting.In addition to invited keynote lectures, the conference program consisted of sessions with talks, panel discussions and poster presentations from researchers and practitioners worldwide, selected through a two-step peer-review process. The conference topics included daylight and electric light in architecture, art, and urban design, organized into four broad categories: Light and Health for all Species, Designing for Darkness, Sensory and Spatial Perceptions, Variability and Rhythmicity.These proceedings include 32 conference papers that were presented either as talks or posters during LS2023. All papers were reviewed by an international panel of reviewers. We thank all reviewers and our partner organizations for their time and help.We also thank the following organizations for their support of LS2023, and for enabling documentation through recordings and proceedings: The Swedish Energy Agency, Bertil & Britt Svenssons Stiftelse för Belysningsteknik, as well as Helvar, Selux, Fergin, Nordic LED, Stockholm Lighting, Annell, Fox Belysning, Optoga.The LS2023 Local Organizing Committee and Proceedings Editorial Team: Ute Besenecker, Foteini Kyriakidou, Gerhard Rehm, Hamidreza Eizadi, Federico Favero, Rodrigo Muro, Johanna Enger, Stavroula Angelaki, Seren DincelList of Reviewers are available in this Pdf.

A Study on Shield Design Aspects of a Semi-Industrial Co-60 Gamma Irradiation Facility at Gamma Source Division of Institute of Food and Radiation Biology of the Bangladesh Atomic Energy Commission

The aim of this work is to investigate the existing shield design aspects of a semi-industrial Cobalt- 60 Gamma Irradiation Facility for 100 kCi, designed for irradiation of pharmaceutical products and daily foodstuffs as well as for research and development purposes at the Institute of Food and Radiation Biology (IFRB) of the Bangladesh Atomic Energy Commission. Earlier, the initial activity of this facility was 65 kCi and stone based reinforced concrete (SBRC) of density 2.60 g/cc and specific thicknesses were used to shield the facility for safety to operational personnel and outside public. Due to a large demand for irradiation of pharmaceutical products as well as of daily foodstuffs, IFRB has decided to increase the initial activity up to 100 kCi for this facility. For this reason, the shielding design aspects of this facility were needed to be recalculated and checked for safety. This analysis was done using the Point-kernel Shielding Code Micro-Shield 5.05 and public domain Point-kernel Shielding code QAD-CGGP2 respectively considering the radiation worker dose limit of 10 μSv/hr of the International Commission on Radiological Protection, ICRP-60, 1990. The corresponding dose limit for public at large is 0.5 μSv/hr. The calculated dose rates at different locations around the facility are far below 10 μSv/hr except in one area. This location is inside the source room. No one is allowed to enter the room when the facility is in the ON mode. However, except one location, positions outside the facility have dose rates about 3 time higher than 0.5 μSv/hr, the dose limit for public at large. Therefore, this analysis shows that the existing shield design aspects of IFRB’s Co-60 gamma source room is safe for a 100 kCi source from the viewpoint of radiation safety to operating personnel but not for public at large within proximity of the facility.

Enhancing Common Bean Tolerance to Short-term Droughts at the Reproductive Stage using a Soil Fertility Management Approach

Aims: This study was conducted to enhance the tolerance of common beans to drought events occurring at the reproductive stage, from a soil improvement perspective.
 Study Design: Split plot completely randomized design was used.
 Place and Duration of Study: Study was conducted in a screen-house at the Legumes and Oil Seeds Division of CSIR-Crops Research Institute, Ghana, from September 2021 to January 2022.
 Methodology: Municipal Solid Waste Compost and inorganic fertilizer combinations were applied to common beans in a pot experiment. They included control, full rate compost (FRAC), full rate fertilizer (NPK 5:30:30 kg/ha) (FRG), FRG + half rate compost (HRAC) and FRG + FRAC. All soils were maintained at 80% field capacity (FC) from the start of the experiment. At flowering, two groups of plants were water stressed till 40 and 16% FC and returned to 80% FC till physiological maturity, while one group maintained 80% FC throughout study. Forty-five soil samples each and plant data were collected at 3, 7 and 10 weeks after planting. Samples were analyzed for soil organic matter (SOM) and water retention, soil nutrients, crop growth, yield and nutrient uptake. Water and nitrogen use efficiencies (W/NUE) were calculated after harvest.
 Results: During the growing period, highest soil moisture (6-9 cm3/cm3) was retained by FRG and FRG+HRAC, FRG+FRAC; 20-38% more than FRAC and control but was not influenced by SOM. While FRG influenced the highest yield and WUE, combining it with compost rates reduced yield by 56-84% and WUE by 55-64%. WUE correlated positively with NUE.
 Conclusion: Antagonistic effect observed with integrating compost with FRG is likely because compost was not properly cured and immobilized soil nitrogen. Farmers can mitigate short-term drought effects on common beans with adequate nutrient supply through fertilizer application; however, fertilizer should only be integrated with compost after compost quality analysis.

Stability of Iodine in Differently Iodised Salts

Iodine deficiency is a public health problem worldwide. Iodization of salt is a valuable technique to overcome iodine insufficiency. There are, however, problems in uniform iodization of salt. The study was conducted to investigate comparative stability and uniformity of mixing of iodine in iodized salt fortified with aqueous solution of KIO3 (powder grade salt) or the same compound added additionally in dry form (granular grade salt). The research study was conducted in the laboratory of Nutrition, Section of the Food science Division of Nuclear institute for Food and Agriculture (NIFA), Peshawar. Salt samples were prepared in a medium sized salt crushing facility at Lahore. These samples were transported in bulk packing to Nuclear Institute for Food and Agriculture (NIFA), Peshawar. Following 3 types of samples will be prepared; powder grade salt fortified with 50 ppm of iodine as KIO3 solution using drip system, granular grade salt iodized with the same system without additional KIO3 (this grade of iodized salt always lacks complete and homogeneous iodization and needs addition of more iodine to attain the 50 ppm level) and granular grade salt iodized with additional KIO3 to make up the total to 50 ppm. the salt samples were packed in high density polyethylene (HDPE) and low density polyethylene (LDPE) packing separately. Analysis was carried out at the initial stage (0day) and subsequently at monthly interval up to fourth month. By standard iodometric titration all collected salt samples were tested for their iodine levels. Data were statistically analyzed using Statistix version 8.0. ANOVA were worked out by completely randomized design with factorial arrangement. Means were separated using Tucky HSD test. The mean moisture contents of salt packed in LDPE and HDPE varied significantly (P < 0.05), salt packed in LDPE showed higher average moisture contents than the salts packed in HDPE. Effect of iodization type was also significant (P<0.05) on the moisture contents of the salts. Granular salt iodized with drip and additional dry KIO3 had the highest moisture contents followed by granular salt iodized with drip system and the lowest moisture content was exhibited by powdered salt iodized with drip system only. The mean moisture contents of salt during different storage intervals were significantly (P < 0.05) different from each other, except during third and four month, With the salt showing higher average moisture contents during the last month and lowest in the first month. Effect of iodization type was also significant (P<0.05) on the moisture contents of the salt. Granular salt iodized with drip and additional dry KIO3 had the highest moisture contents followed by granular salt iodized with drip system and the lowest moisture content was exhibited by powdered salt iodized with drip system only. The mean moisture contents of salt during different storage periods were significantly (P < 0.05) different from each other, except during third and four month. The salt showed higher average moisture contents during the last month and lowest in the first month. Effect of packing material type was also significant (P<0.05) on the moisture contents of the salt. The mean moisture contents of salt packed in LDPE and HDPE varied significantly (P < 0.05).However, salt packed in LDPE showed higher average moisture contents than that of salts packed in HDPE. The powder salt retained iodine better than the other two salts types used. The iodine retention gradually decreased during storage periods. Among the packaging material used the salt in low density polyethylene showed higher moisture content. During storage intervals the average moisture content increased. The granular salt (grade II) showed maximum moisture content among the three salt types

Estimation and comparison of different lactation persistency methods in Tharparkar cattle

The present study was undertaken to estimate the various measures of lactation persistency and to estimate effect of various non-genetic factors affecting the persistency of milk production and comparison of different persistency indices using standard error as percentage of mean in Tharparkar cattle. Total 322 lactation records of 138 Tharparkar cattle were collected from Animal Genetics and Breeding Division of National Dairy and Research Institute, Karnal from 1996 to 2018 for the estimation of lactation persistency. Lactation persistency was estimated using Ratio method (P1), Prasad method (P2), Solkner and Fuchs variation method in 200 days (P3) and 305 days (P4).The least squares of means for persistency of milk yield were 149.6 ± 3.07, 0.53 ± 0.007, 1.83 ± 0.05 and 2.28 ± 0.07 in P1, P2, P3 and P4 respectively in Tharparkar cattle. Based on standard error as percentage of mean, the best method was Prasad method (1.1%). The highest values of least squares means were found for first calvers in P1 but in P3 and P4 fourth calvers were more persistent. The cows calved during rainy season were more persistent as estimated by P1 and P2 but based on P3 and P4 winter calvers were more persistent. There was a highly significant (P<0.05) positive correlation of total milk yield with all the method of persistency indices.

Influence of clipping of North Caucasian Meat and Wool breed sheep before lambing on wool productivity of ewes and their offspring

Over the past 20 years, various scientists have conducted a number of researches on the effect of clipping before lambingon the wool productivity of sheep of different breeds and in different climatic conditions. The authors studied the effect of clipping before lambing on the milk production of ewes, studied the growth and development of lambs, the dynamics of live weight and the livability of young animals. The accumulated data allowed us to conclude that the use of clipping before lambing increases the productive performance of animals. However, these studies were fragmentary and did not have a systematic nature, so for these and other reasons they were not adopted by sheep breeders. The work on the infl uence of clipping before lambingon the wool productivity of the sheep of North Caucasian Meat and Wool breed has been carried out in the experimental division of the All-Russian Research Institute of Sheep and Goat Breeding. The purpose of the research was to determine the effect of late-autumn (November) insemination and clipping before lambing (3 weeks before lambing) of the sheep of North Caucasian Meat and Wool breed on the quality characteristics of the wool of ewes and their off spring. In accordance with the research methodology 2 groups of pregnant ewes have been selected, the formation of which has been carried out on the principle of analogues in age and live weight. In the 1st group (control) 100 heads were selected and have been clipping in the traditional terms after lambing (early June), in the 2nd group (experimental) 100 heads that were clipping three weeks before lambing (early April). It has been found in our studies that clipping ewes 21 days before lambing has a positive effect on the wool productivity of the resulting off spring. As the result of better growth and development of young animals, more intensively receive nutrients to the hair follicles, so most of them produce wool fiber.
