Bundelkhand region of central India, a major drought affected area of the country is associated to high level of rural to urban migration. The present study was conducted to analyze the socio-economic characteristics of the migrants and to examine the key factors triggering migration decision of agriculture practicing households. The region was facing drought for the fourth consecutive period which had left the population, mainly dependent on agricultural income, out of option than migration. The analysis of socio-economic profile of migrants showed that majority of the migrants were between the age group of 20–39 (70.1%) and the education level was secondary (54.8%). The population of female migrants was comparatively low, as many of them followed their family to the migrating place after marriage. Majority of the migrants (81.73%) were engaged in unskilled manual labour activities like construction works in destination cities. The various factors identified triggering migration decision were associated to livelihood security, climatic, agricultural, institutional and socio-cultural factors.

Wheat is the most important cereal crop and staple diet for more than one third of the world population and contributes more calories and protein to the world diet than any other cereal crop. In view of global climate change drought stress is becoming major constraints for the productivity of wheat and hence the breeding for drought tolerance is gaining more importance. More accurate and precise phenotyping of genetic resources is the demand of the new generation quantitative geneticists and plant breeders as this is the most critical research area which will lead to identification of trait specific donor germplasm. In the present study, Wheat germplasm accessions (1483 acc.) were evaluated at Issapur farm in Augmented Block Design with four checks based on morpho-physiological parameters. Irrigation was provided at Crown root initiation stage (CRI) and afterwards moisture deficit was maintained throughout the crop duration. There was wide variability in wheat germplasm for the phonological, agronomical and physiological traits. This experiment identified correlated traits responsible for high grain yield under rainfed conditionsuch as biological yield, harvest index, days to maturity, spike length, spikelets per spike, grains per spike, cholorophyll content, grain weight and 1000 grain weight. Based on stepwise multiple regression analysis, major role of prediction on yield was found through biological yield, including harvest index, grain weight spikelets per spike and chlorophyll content. Based on predictor variables, accessions were selected and will be further validated under controlled condition and will be used for introgression purpose in the background of elite varieties to enhance yield and its stability under moisture stress environments.

Field experiments were conducted at eleven centers of All India Coordinated Research Project on Potato located in different agro-climatic zones to investigate the role of phosphobacteria in P economy in potato crop during 2005–06 and 2006–07. Six treatments consisting of combinations of different levels of P as well as phosphobacteria (PSB) used in the study showed significant effect on yield of potato. At Kalyani, Chhindwara, Kota, Patna, Hassan and Ooty, recommended dose of NK + 75% P + PSB was statistically at par with recommended dose of NPK in term of total yield. At Bhubaneshwar, Dholi, Hisar, Deesa and Modipuram, 75% of fertilizer P + PSB either had no significant effect on potato tuber yield or reduced the yield marginally in two years of experimentations. Net returns with recommended NPK or 75% P + PSB showed the best results at most of the centers. The per cent saving of fertilizer P, calculated using quadratic model, was maximum for Hassan (43%). In general, use of PSB saved around 20 to 25% P, depending upon agro-ecological situations and soil conditions. However, at Bhubaneshwar, Kota and Dholi the saving being very meager was not economical. The results clearly indicate the role of PSB in saving fertilizer P across different agro-climatic zones, However, it also came out very clearly that effectiveness of the PSB depends on agro-ecological situations and soil conditions.

- Abstract
Understanding the epigenetic molecular mechanisms (EMMs) of reproduction is crucial for developing advanced and targeted control strategies for Spodoptera frugiperda. Differential expression analysis revealed 11 known miRNAs with varying expression levels, including nine upregulated and two downregulated miRNAs, in virgin females compared with males. The predictive analysis identified 426 target genes for these miRNAs, with ribogenesis highlighted as a key process in oogenesis and egg fertilization. This study also investigated the expression of miRNAs in both virgin and mated male and female S. frugiperda, with a focus on their roles in reproduction. A strong negative correlation was observed between miRNA expression levels and their target hub genes, confirming the transcriptional regulation by miRNAs. Additionally, protein-protein interaction (PPI) network identified the gene CG5033 (BOP1), as a central hub, was also predicted to be the target of miR-92a-3p in S. frugiperda, is involved in the maturation of large ribosomal RNA subunits. This study further provided experimental evidence that either the depletion of miR-92a-3p in virgin females or the knockdown of BOP1 in virgin males led to the production of infertile eggs post-mating. These findings validate the regulatory role of the miR-92a-3p - BOP1 interaction and underscore its importance in oogenesis and fertilization., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2025 Elsevier B.V.

- Abstract
Label-free proteomics expression data sets often exhibit data heterogeneity and missing values, necessitating the development of effective normalization and imputation methods. The selection of appropriate normalization and imputation methods is inherently data-specific, and choosing the optimal approach from the available options is critical for ensuring robust downstream analysis. This study aimed to identify the most suitable combination of these methods for quality control and accurate identification of differentially expressed proteins. In this study, we developed nine combinations by integrating three normalization methods, locally weighted linear regression (LOESS), variance stabilization normalization (VSN), and robust linear regression (RLR) with three imputation methods: k-nearest neighbors (k-NN), local least-squares (LLS), and singular value decomposition (SVD). We utilized statistical measures, including the pooled coefficient of variation (PCV), pooled estimate of variance (PEV), and pooled median absolute deviation (PMAD), to assess intragroup and intergroup variation. The combinations yielding the lowest values corresponding to each statistical measure were chosen as the data set's suitable normalization and imputation methods. The performance of this approach was tested using two spiked-in standard label-free proteomics benchmark data sets. The identified combinations returned a low NRMSE and showed better performance in identifying spiked-in proteins. The developed approach can be accessed through the R package named 'lfproQC' and a user-friendly Shiny web application (https://dabiniasri.shinyapps.io/lfproQC and http://omics.icar.gov.in/lfproQC), making it a valuable resource for researchers looking to apply this method to their data sets.

- Abstract
Rice blast disease, instigated by Magnaporthe oryzae ( M. oryzae ), significantly impedes global rice production. Targeting the M. oryzae signaling protein, cAMP-Protein Kinase A (CPKA), which facilitates appressorium development and host penetration, this study explores the potential inhibitory effects of natural compounds. Virtual screening, molecular docking and text mining approaches were used to find the nimonol and curcumin that inhibit the CPKA protein. The MM-PBSA method was used to do the molecular dynamics (MD) simulation and the binding free energy analysis of the molecule. Their binding free energies (ΔG
bind ) of -78.81 kJ/mol and -117.65 kJ/mol, respectively, point to the potential efficacy of the CPKA-nimonol and CPKA-curcumin complexes as inhibitors. The inhibitory effects have been further verified by various MD analysis. This study emphasizes the need to conduct further study on the CPKA protein and gives important insights into the possibility of natural compounds as M. oryzae inhibitors.- Published

- Abstract
The squash species Cucurbita moschata has been historically utilized by both animals and humans as a food source. It is an annual dicotyledonous vegetable known for its health benefits, including reducing the risk of various diseases, such as cancer, high blood pressure, diabetes, intestinal disorders, and atherosclerosis, in humans. However, the cultivation of this valuable crop is often challenged by diseases such as powdery mildew (PM), caused by the fungus Podosphaera xanthii . PM not only reduces yield but also impacts photosynthesis rates. A newly identified gene called CmoCh3G009850 , which encodes the transcription factor known as AP2-like ethylene-responsive factor (CmoAP2/ERF), has been marked for resistance against PM. A shift in the state from susceptible to resistant can be induced by nonsynonymous SNP mutations at five locations of the CmoCh3G009850 gene. The dynamical studies of the wild-type (WT) and mutated-type AP2/ERF proteins' interactions with DNA were explored by docking and molecular dynamics simulation studies. These five mutations T105A, S302R, H321R, H335D, and V402A are incorporated in the AP2/ERF transcription factor that makes a stable and compact complex with DNA rather than the WT protein. Overall, the identification and characterization of the CmoAP2/ERF gene and its variants represent a significant advancement for the breeding and cultivation of C. moschata varieties resistant against powdery mildew. This study not only enhances our understanding of plant-pathogen interactions but also provides a potential avenue for developing more resilient squash varieties through genetic improvement., Competing Interests: The authors declare no competing financial interest., (© 2024 The Authors.

- Abstract
In insect genome editing CRISPR/Cas9 is predominantly employed, while the potential of several classes of Cas enzymes such as Cas12a largely remain untested. As opposed to Cas9 which requires a GC-rich protospacer adjacent motif (PAM), Cas12a requires a T-rich PAM and causes staggered cleavage in the target DNA, opening possibilities for multiplexing. In this regard, the utility of Cas12a has been shown in only a few insect species such as fruit flies and the silkworm, but not in non-model insects such as the fall armyworm, Spodoptera frugiperda, a globally important invasive pest that defies most of the current management methods. In this regard, a more recent genetic biocontrol method known as the precision-guided sterile insect technique (pgSIT) has shown successful implementation in Drosophila melanogaster, with certain thematic adaptations required for application in agricultural pests. However, before the development of a controllable gene drive for a non-model species, it is important to validate the activity of Cas12a in that species. In the current study we have, for the first time, demonstrated the potential of Cas12a by editing an eye color gene, tryptophan 2,3-dioxygenase (TO) of S. frugiperda by microinjecting ribonucleoprotein complex into pre-blastoderm (G0) eggs. Analysis of G0 mutants revealed that all five mutants (two male and three female) exhibited distinct edits consisting of both deletion and insertion events. All five edits were further validated through in silico modeling to understand the changes at the protein level and further corroborate with the range of eye-color phenotypes observed in the present study., Competing Interests: Declarations.

- Abstract
Developing early maturing lentil has the potential to minimize yield losses, mainly during terminal drought. Whole-genome resequencing (WGRS) based QTL-seq identified the loci governing earliness in lentil. The genetic analysis for maturity duration provided a good fit to 3:1 segregation (F
2 ), indicating earliness as a recessive trait. WGRS of Globe Mutant (late parent), late-flowering, and early-flowering bulks (from RILs) has generated 1124.57, 1052.24 million raw and clean reads, respectively. The QTL-Seq identified three QTLs (LcqDTF3.1, LcqDTF3.2, and LcqDTF3.3) on chromosome 3 having 246244 SNPs and 15577 insertions/deletions (InDels) and 13 flowering pathway genes. Of these, 11 exhibited sequence variations between bulks and validation (qPCR) revealed a significant difference in the expression of nine candidate genes (LcGA20oxG, LcFRI, LcLFY, LcSPL13a, Lcu.2RBY.3g060720, Lcu.2RBY.3g062540, Lcu.2RBY.3g062760, LcELF3a, and LcEMF1). Interestingly, the LcELF3a gene showed significantly higher expression in late-flowering genotype and exhibited substantial involvement in promoting lateness. Subsequently, an InDel marker (I-SP-383.9; LcELF3a gene) developed from LcqDTF3.2 QTL region showed 82.35% PVE (phenotypic variation explained) for earliness. The cloning, sequencing, and comparative analysis of the LcELF3a gene from both parents revealed 23 SNPs and InDels. Interestingly, a 52 bp deletion was recorded in the LcELF3a gene of L4775, predicted to cause premature termination of protein synthesis after 4 missense amino acids beyond the 351st amino acid due to the frameshift during translation. The identified InDel marker holds significant potential for breeding early maturing lentil varieties., (© 2024 The Author(s).

- Abstract
Background: To treat diseases like cancer, conventional Paclitaxel (PTX)- based monotherapy treatment regimens are becoming less effective due to the development of resistance. In this aspect, the phytomolecule curcumin (Cur), having ethnopharmacological importance in traditional South Asian remedies, like Ayurveda and Chinese traditional medicine, has been studied as a promising chemo-sensitizing and synergistic partner of PTX., Aim: This study aimed to evaluate the combined effect of PTX and Cur compared to PTX therapy alone in the in vitro and in vivo environments., Material and Methods: An extensive PubMed search was performed wherein 169 papers were shortlisted and screened to identify 30 studies that have reported the effect of PTX and Cur either in vitro, in vivo, or both. The pooled Odds Ratio (OR) was calculated at a 95% Confidence Interval (CI) for determining the effect of combination therapy., Results: The meta-analysis has indicated PTX and Cur combination therapy to be associated with a significant decrease in cell viability (OR: 0.37, 95% CI: 0.27-0.51; p < 0.01) and tumor volume (OR: 0.32, 95% CI: 0.15-0.71; p = 0.01). Additionally, the effect of this combination on drug-resistant cell lines has exhibited a significant decrease in the odds of cell viability (OR: 0.45, 95% CI: 0.35-0.57; p < 0.01)., Conclusion: Overall, the current meta-analysis has shown PTX and Cur combination to effectively inhibit the viability of cancer cells, reduce tumor volume, and diminish the growth of drug-resistant cancer cells., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

- Abstract
MicroRNAs are key players involved in stress responses in plants and reports are available on the role of miRNAs in drought stress response in rice. This work reports the development of a database, RiceMetaSys: Drought-miR, based on the meta-analysis of publicly available sRNA datasets. From 28 drought stress-specific sRNA datasets, we identified 216 drought-responsive miRNAs (DRMs). The major features of the database include genotype-, tissue- and miRNA ID-specific search options and comparison of genotypes to identify common miRNAs. Co-localization of the DRMs with the known quantitative trait loci (QTLs), i.e., meta-QTL regions governing drought tolerance in rice pertaining to different drought adaptive traits, narrowed down this to 37 promising DRMs. To identify the high confidence target genes of DRMs under drought stress, degradome datasets and web resource on drought-responsive genes (RiceMetaSys: DRG) were used. Out of the 216 unique DRMs, only 193 had targets with high stringent parameters. Out of the 1081 target genes identified by Degradome datasets, 730 showed differential expression under drought stress in at least one accession. To retrieve complete information on the target genes, the database has been linked with RiceMetaSys: DRG. Further, we updated the RiceMetaSys: DRGv1 developed earlier with the addition of DRGs identified from RNA-seq datasets from five rice genotypes. We also identified 759 putative novel miRNAs and their target genes employing stringent criteria. Novel miRNA search has all the search options of known miRNAs and additionally, it gives information on their in silico validation features. Simple sequence repeat markers for both the miRNAs and their target genes have also been designed and made available in the database. Network analysis of the target genes identified 60 hub genes which primarily act through abscisic acid pathway and jasmonic acid pathway. Co-localization of the hub genes with the meta-QTL regions governing drought tolerance narrowed down this to 16 most promising DRGs.

- Abstract
The cell wall of the Glycine max altered by the polygalacturonases (PGs) secreted by the fungus Sclerotinia sclerotiorum, causes disease and quality losses. In soybeans, a resistance protein called polygalacturonases-inhibiting proteins (PGIPs) binds to the PG to block fungal infection. The active site residues of PGIP3, VAL170 and GLN242 are mutated naturally by various amino acids in different types of PGIPs. Therefore, the mutation of VAL170 to GLY is ineffective but the GLN242 amino acid mutation by LYS significantly alters the structure and is crucial for interacting with the PG protein. Docking and Molecular Dynamics simulation provide a comprehensive evaluation of the interactions between gmPGIP and ssPG. By elucidating the structural basis of the interaction between gmPGIP and ssPG, this investigation lays a foundation for the development of targeted strategies in-order to enhance soybean resistance against Sclerotinia sclerotiorum . By leveraging this knowledge, researchers can potentially engineer soybean varieties with improved resistance to the fungus, thereby reducing disease incidence and improving crop yields., (© 2024 The Author(s).)

- Abstract
Invasive insect pests, currently, pose a serious economic threat to several staple crops all over the world, one such being the fall armyworm, Spodoptera frugiperda. It was first observed in Africa since 2016, outside of its natural habitat in the Americas. Subsequently, it invaded several countries in South and South East Asia and also very recently in Australia. In all the newly invaded regions, maize is the principal crop attacked causing a serious economic concern to the poor farmers, particularly in the developing countries. Owing to the innate genetic ability, it defies many of the management options that include insecticides, Bt transgenics, and so forth. This is due to its high mobility, polyphagy and ability for quick development of resistance to several classes of insecticides. At this critical juncture, CRISPR/Cas9 mediated genome editing has shown a lot of promise in developing a novel area-wide pest management strategy called precision-guided sterile insect technique (pgSIT). pgSIT was initially demonstrated in Drosophila melanogaster which holds a greater promise for the environmentally friendly management of several globally significant agricultural pests such as S. frugiperda. Therefore, before developing both sgRNA and Cas9 transgenic lines, we have validated the target gene such as tssk2 through a non-transgenic approach by microinjecting ribo nucleo protein complex (Cas9 protein and tssk2 sgRNA) into G
0 eggs of S. frugiperda. In the current investigation, we have obtained five edited males with distinct mutations which were further used for crossing studies to ascertain the effect of tssk2 editing affecting egg hatchability., (© 2024 Wiley Periodicals LLC.)- Published

- Abstract
India is largely import dependent in meeting its domestic demand of edible oils. This study aims to discuss the consequences of recent global events such as COVID-19 and the Russia-Ukraine war on edible oil imports. Due to prevailing supply chain disruptions and local shortages in significant supplier countries, international prices became highly volatile, and import volumes were hit severely. This led to an almost doubling of the cost of imports from US $ billion 9.52 in 2019-20 to US $18.70 billion in 2021-22, putting an enormous burden on the Indian exchequer. Overall, an increase in the price of all edible oils has been recorded since the later parts of 2021, exerting inflationary pressure on the food price index. As edible oils are part of staple diets, the import dependency of such a large magnitude makes India extremely vulnerable to external shocks. This calls for immediate attention to the issue of self-sufficiency (atma nirbharata) in edible oils production by emphasizing long-term measures., Competing Interests: Conflict of interestsThe authors declare that they have no conflict of interest., (© The Author(s), under exclusive licence to The National Academy of Sciences, India 2023.)

- Abstract
Kinnow ( Citrus nobilis Lour. × Citrus deliciosa Ten.) needs to be genetically improved for traits such as seedlessness using biotechnological tools. Indirect somatic embryogenesis (ISE) protocols have been reported for citrus improvement. However, its use is restricted due to frequent occurrences of somaclonal variation and low recovery of plantlets. Direct somatic embryogenesis (DSE) using nucellus culture has played a significant role in apomictic fruit crops. However, its application in citrus is limited due to the injury caused to tissues during isolation. Optimization of the explant developmental stage, explant preparation method, and modification in the in vitro culture techniques can play a vital role in overcoming the limitation. The present investigation deals with a modified in ovulo nucellus culture technique after the concurrent exclusion of preexisting embryos. The ovule developmental events were examined in immature fruits at different stages of fruit growth (stages I-VII). The ovules of stage III fruits (>21-25 mm in diameter) were found appropriate for in ovulo nucellus culture. Optimized ovule size induced somatic embryos at the micropylar cut end on induction medium containing Driver and Kuniyuki Walnut (DKW) basal medium with kinetin (KIN) 5.0 mg L
-1 and malt extract (ME) 1,000 mg L-1 . Simultaneously, the same medium supported the maturation of somatic embryos. The matured embryos from the above medium gave robust germination with bipolar conversion on Murashige and Tucker (MT) medium + gibberellic acid (GA3 ) 2.0 mg L-1 + ά-naphthaleneacetic acid (NAA) 0.5 mg L-1 + spermidine 100 mg L-1 + coconut water (CW) 10% (v/v). The bipolar germinated seedlings established well upon preconditioning in a plant bio regulator (PBR)-free liquid medium under the light. Consequently, a cent percent survival of emblings was achieved on a potting medium containing cocopeat:vermiculite:perlite (2:1:1). Histological studies confirmed the single nucellus cell origin of somatic embryos by undergoing normal developmental events. Eight polymorphic Inter Simple Sequence Repeats (ISSR) markers confirmed the genetic stability of acclimatized emblings. Since the protocol can induce rapid single-cell origin of genetically stable in vitro regenerants in high frequency, it has potential for the induction of solid mutants, besides crop improvement, mass multiplication, gene editing, and virus elimination in Kinnow mandarin., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Murugan, Awasthi, Singh, Chawla, Solanke, Kumar and Jha.)- Published

- Abstract
Aluminum-doped zinc oxide (AZO) is a popular, low-cost, nontoxic material that finds application as a transparent conducting electrode in photonic, sensing, and photovoltaic devices. We report the AZO thin films with a high figure of merit on large-area glass substrates by direct current magnetron sputtering without any intentional substrate heating. Furthermore, a simple thermal post-treatment to improve the transmittance of AZO thin film in the infrared region for its application in low-band-gap devices is presented. High optoelectronic properties are obtained by optimizing oxygen content during the sputtering process. The structural, morphological, optoelectrical, and photoluminescence characterization of cold sputtered AZO films is investigated for its latent applications. AZO thin films with an electrical sheet resistance of 8.8 Ω/□ and a visible light transmittance of 78.5% with thickness uniformity above 95% are achieved on 300 mm × 300 mm glass substrate. The AZO film with optimized process conditions is employed as a transparent electrode to fabricate a copper-indium-gallium-selenide-based thin film solar cell, demonstrating 11.8% power conversion efficiency. The AZO film with optimized sputter conditions was post-treated in ambient conditions with an Al blanket to suppress the resistivity by proper organization of the defects due to Al
3+ consumption and point defects, resulting in improved transparency (85%) in the infrared region with a sheet resistance of 40 Ω/□. This has great potential for developing scalable and low-cost AZO thin films for transparent electrodes in a wide range of the spectrum., Competing Interests: The authors declare no competing financial interest., (© 2022 The Authors.

- Abstract
Cultivars with efficient root systems play a major role in enhancing resource use efficiency, particularly water absorption, and thus in drought tolerance. In this study, a diverse wheat association panel of 136 wheat accessions including mini core subset was genotyped using Axiom 35k Breeders' Array to identify genomic regions associated with seedling stage root architecture and shoot traits using multi-locus genome-wide association studies (ML-GWAS). The association panel revealed a wide variation of 1.5- to 50-fold and were grouped into six clusters based on 15 traits. Six different ML-GWAS models revealed 456 significant quantitative trait nucleotides (QTNs) for various traits with phenotypic variance in the range of 0.12-38.60%. Of these, 87 QTNs were repeatedly detected by two or more models and were considered reliable genomic regions for the respective traits. Among these QTNs, eleven were associated with average diameter and nine each for second order lateral root number (SOLRN), root volume (RV) and root length density (RLD). A total of eleven genomic regions were pleiotropic and each controlled two or three traits. Some important candidate genes such as Formin homology 1, Ubiquitin-like domain superfamily and ATP-dependent 6-phosphofructokinase were identified from the associated genomic regions. The genomic regions/genes identified in this study could potentially be targeted for improving root traits and drought tolerance in wheat.

- Abstract
Educational institutes across the world have closed due to the COVID-19 pandemic jeopardizing the academic calendars. Most educational institutes have shifted to online learning platforms to keep the academic activities going. However, the questions about the preparedness, designing and effectiveness of e-learning is still not clearly understood, particularly for a developing country like India, where the technical constraints like suitability of devices and bandwidth availability poses a serious challenge. In this study, we focus on understanding Agricultural Student's perception and preference towards the online learning through an online survey of 307 students. We also explored the student's preferences for various attributes of online classes, which will be helpful to design effective online learning environment. The results indicated that majority of the respondents (70%) are ready to opt for online classes to manage the curriculum during this pandemic. Majority of the students preferred to use smart phone for online learning. Using content analysis, we found that students prefer recorded classes with quiz at the end of each class to improve the effectiveness of learning. The students opined that flexibility and convenience of online classes makes it attractive option, whereas broadband connectivity issues in rural areas makes it a challenge for students to make use of online learning initiatives. However, in agricultural education system where many courses are practical oriented, shifting completely to online mode may not be possible and need to device a hybrid mode, the insights from this article can be helpful in designing the curriculum for the new normal., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2020 The Authors.)

- Abstract
Introduction: Chronic ACL insufficiency with associated varus malalignment due to knee osteoarthritis (OA) is challenging to treat surgically. A combined ACL reconstruction (ACLR) with medial open wedge high tibial osteotomy (HTO) without using any metallic implant for HTO is an effective technique., Materials and Method: All the patients attending the outpatient department ACL injury and with associated medial compartment OA (Kellegren's grade 2 and grade 3) were considered for inclusion in the study. Forty patients who met inclusion criteria were included in the study. Simultaneous ACLR (single bundle of quadrupled hamstring graft fixed with Endobutton on femoral side and biointerference screw on the tibial side) along with medial opening wedge osteotomy (with tricalcium phosphate wedge) was done. The patients were assessed with IKDC, KOOS scores and any change in anterior tibial translation was also checked., Results: The combined procedure showed mean varus angle correction of 9° (10.5-1.5°), and the mechanical axis of the knee was restored from an average of 172-181.5°. There was a significant improvement in knee score (KOOS and IKDC) after the surgery ( p < 0.05). The average time for the radiological union of the osteotomy was 3.56 months. The anterior tibial translation was improved. No intraoperative complications and slippage of the synthetic graft were noted in any case., Conclusions: Combined ACLR with HTO (using TCP wedge, without any hardware) is a reliable method that prevents rapid progression of OA. It reliably corrects varus deformity and obviates the use of any hardware.

- Abstract
Background: Fracture of the capitellum is an often missed or inadequately treated serious elbow injury. Anatomic reduction and proper stabilization are essential to obtain articular congruity so that late-onset arthritis can be avoided. The main areas of interest in this intriguing fracture are the choice of implant and the surgical approach. We describe the use of anterolateral approach and headless double-threaded compression screws for the fixation of this fracture., Materials and Methods: This prospective study included 16 capitellar fractures. A computed tomography scan was done for delineating the fracture line and planning the fixation technique. All fractures were treated with headless double-threaded compression screws using an anterolateral approach, over a period of 3 years, with a mean follow-up of 2.3 years (range, 1.5-4 years)., Results: The average time to bony union was 3.5 months (range, 2.5-5 months) with no malunion or nonunion. The mean range of flexion was 132° (range, 125°-135°). The average extensor lag was 10° (range, 0°-25°), but the range of motion remained functional in all patients. On the final follow-up, no evidence of osteonecrosis, post-traumatic osteoarthritis, or heterotrophic ossification was seen. The outcome was excellent in 10 patients, and 6 patients had a good result., Conclusions: The success of management of a capitellar fracture depends on an early diagnosis by keeping a high index of suspicion and timely management. Adequate exposure of the fracture is of paramount importance to achieve accurate reduction. This can be satisfactorily achieved by an anterolateral approach to the elbow. An adequate fixation of the fractured fragments can be achieved by the use of headless double-threaded compression screws., (Copyright © 2016 Journal of Shoulder and Elbow Surgery Board of Trustees.

- Abstract
Usher syndrome is a group of autosomal recessive disorders characterised by progressive visual loss from retinitis pigmentosa and moderate to severe sensorineural hearing loss. Usher syndrome is estimated to account for 6-10% of all congenital sensorineural hearing loss. A gene locus in Usher type II (USH2) families has been assigned to a small region on chromosome 1q41 called the UHS2A locus. We have investigated two families with Usher syndrome from different isolated populations. One family is a Norwegian Saami family and the second family is from the Cayman Islands. They both come from relatively isolated populations and are inbred families suitable for linkage analysis. A lod score of 3.09 and 7.65 at zero recombination was reached respectively in the two families with two point linkage analysis to the USH2A locus on 1q41. Additional homozygosity mapping of the affected subjects concluded with a candidate region of 6.1 Mb. This region spans the previously published candidate region in USH2A. Our study emphasises that the mapped gene for USH2 is also involved in patients from other populations and will have implications for future mutation analysis once the USH2A gene is cloned.
