Mito-Q supplementation of in vitro maturation or in vitro culture medium improves maturation of buffalo oocytes and developmental competence of cloned embryos by reducing ROS production.

Mito-Q is a well-known mitochondria-specific superoxide scavenger. To our knowledge, the effect of Mito-Q on buffalo oocyte maturation and developmental competency of cloned embryos has not been examined. To investigate the effects of Mito-Q on the in vitro maturation (IVM) of buffalo oocytes and the developmental competence of cloned embryos, different concentration of Mito-Q were supplemented with IVM (0, 0.1, 0.5, 1, 2 µM) and in vitro culture (IVC) medium (0, 0.1 µM). Supplementation of IVM medium with 0.1 µM Mito-Q significantly (P ≤ 0.05) increased the cumulus expansion, nuclear maturation, mitochondrial membrane potential (MMP) and antioxidants genes (GPX1 and SOD2) expression and effectively reduced ROS production leading to a significant improvement in the maturation rate of buffalo oocytes. Further, the supplementation of 0.1 µM Mito-Q in IVC medium promotes the cleavage and blastocyst rate significantly over the control. Mito-Q supplementation improves (P ≤ 0.05) MMP, antioxidant gene (GPX1) expression and reduced the ROS level and apoptosis related genes (caspase 9) expression in cloned blastocysts. In conclusion, the present study demonstrated that the supplementation of 0.1 µM Mito-Q in IVM and IVC media exerts a protective role against oxidative stress by reducing ROS production and improving MMP, fostering improved maturation of buffalo oocytes and enhanced developmental competence of cloned embryos. These findings contribute valuable insights into the optimization of assisted reproductive technologies protocols for buffalo breeding and potentially offer novel strategies to enhance reproductive outcomes in livestock species.

Comparative evaluation of native top feeds of western Himalayas for utilization as goat's ration in mash and block form.

The current research was undertaken to scrutinize the effect of leaf meal mixture as concentrate mixture in the ration of goats. Leaf meal mixture (LMM) was prepared using equal quantities of ten top-foliages namely Acacia nilotica, Celtis australis, Ficus palmata, Ficus religiosa, Grewia optiva, Melia azadarach, Morus alba, Quercus incana, Salix alba and Zizyphus jujube obtained from district Poonch of Jammu region in western Himalayas. The LMM prepared was substituted for 15% in the concentrate mixture being fed to the goats. The study constituted of two trials. Concentrate mixture offered to the animals was in mash and multi-nutrient block in first and second trial respectively. A total of twelve non-descript, adult male goats were selected for each trial. Goats of 0-14 months age (27.71 ± 2.96 kg live body weight) of for first trial while goats of 12-16 months age (27.02 ± 2.93 kg live weight) for second trial were divided into control and treatment groups as per randomized block design and fed ad-lib wheat straw and concentrate mixture @ (20 g/kgW0.75). No significant variation was observed (p > 0.05) in body weight, feed and DM intake among all groups in both trials. Comparable intake as well as digestibility of various nutrients like DM, OM, CP, EE, CF, NFE, NDF, ADF and TDN were found between the two groups during individual trials. There was a positive nitrogen, calcium and phosphorus balance among all experimental animals in both the trials. Serum enzymes ALT, AST and haemato-biochemical parameters like total protein, albumin, globulin, albumin: globulin and blood urea nitrogen (BUN) showed no significant differences during both trials in all groups, being within normal physiological levels. However, haemoglobin concentration was significantly higher (P < 0.05) in treatment group with respect to the control group in first trial. On the basis of current results, it can be established that leaf meal mixture can successfully be used to replace concentrate mixture up to 15% in the ration of goats without expecting any adverse impacts on their growth and overall health.

Functional hBN decorated Ni(OH)2 nanosheets synthesized for remarkable adsorption performance for the elimination of fluoride ions.

Occurrence of fluoride in groundwater is a serious concern due to its fatal effects. Functionalized hexagonal boron nitride sheets have been combined with nickel hydroxide nanoparticles by a one step process and a hybrid adsorbent Ni(OH)2@hBN has been developed with an exceptionally high fluoride adsorption capacity of 365 mg g-1, higher than those of Ni(OH)2 and hBN. This maximum adsorption capacity is higher than those of most common adsorbents used for defluoridation including activated alumina, reported nickel oxide and carbon-based 2D material-supported alumina adsorbents. The presence of functionalized boron nitride significantly increased the surface area to 680 m2 g-1 with a pore volume of 0.33687 cm3 g-1 and provided rich hydroxyl group-containing surface sites for the removal of fluoride present in contaminated water. In addition, the adsorption of fluoride onto boron nitride-modified nickel hydroxide followed pseudo-second-order kinetics and the equilibrium data fitted well with the Langmuir adsorption isotherm, suggesting a monolayer adsorption mechanism. Furthermore, the material developed is tested with the water sample collected from a real affected area, from the Dhar district of India, and the material showed promising results in terms of fluoride removal efficacy.

Genetic analysis for semen quality traits in buffalo bulls.

This study was attempted to estimate the genetic parameters of semen quality traits in buffalo bulls. The study data consisted of 10975 ejaculates from 45 Murrah buffalo bulls (aged 24-72 months) used for breeding program during year 2010 to 2020. Semen quality traits (ejaculate volume, concentration of sperm, mass activity, initial and post-thaw motility, number of sperms per ejaculate, motile sperm number and discard rates) were studied. It was observed that average ejaculate volume was 2.82 ± 1.45 mL with mean concentration of 1040.12 ± 523.26 million/mL. Higher heritability was observed for number of sperms per ejaculate, number of motile sperm and sperm concentration. Significant phenotypic correlation was obtained between volume and number of sperms per ejaculate as well as volume and number of motile sperms. Likewise, significant phenotypic correlation was evident between sperm concentration with sperm number per ejaculate. Highest phenotypic correlation was obtained between sperm count per ejaculate and motile sperm count. Estimated genetic trends showed significant change in volume and motile sperm number. In conclusion, this study ascertains that genetic parameters of semen traits can be considered during the selection of buffalo bulls in breeding program.

Superior Interfacial Contact Yields Efficient Electron Transfer Rate and Enhanced Solar Photocatalytic Hydrogen Generation in M/C3N4 Schottky Junctions.

Various literature studies (Table 6) have reported that dispersion of metal nanoparticles (NPs) on graphitic carbon nitride g-C3N4 (M/CN) has considerably improved the photocatalytic hydrogen yield. It is understood that metal NPs create active sites on the surface of CN and act as a cocatalyst. However, the precise changes induced by different metal NPs on the surface of CN still elude us. Here, we report a thorough understanding and comparison of the morphology, metal-support interactions, interfacial charge transfer kinetics, and band characteristics in different M/CN (M = Pt, Pd, Au, Ag, Cu) correlated with photocatalytic activity. Among all metals, Pt/CN was found to be the best performer both under sunlight and UV-visible irradiation. Under sunlight, maximum H2@ 2.7 mmol/h/g was observed over Pt/CN followed by Pd/CN > Au/CN > Ag/CN > Cu/CN ≈ CN. The present study revealed that among all metals, Pt formed superior interfacial contact with g-C3N4 as compared to other metals. The maximum Schottky barrier height (Φb,Pt) of 0.66 V was observed at Pt/CN followed by Φb,Au/CN (0.46 V) and Φb,Pd/CN (0.05 V). The presence of electron-deficient Pt in Pt-XPS, decrease in the intensity of d-DOS of Pt near the Fermi level in VB-XPS, increase in CB tail states, and cathodic shift in Vfb in MS plots sufficiently confirmed strong metal-support interactions in Pt/CN. Due to the SPR effect, Au and Ag NPs suffered from agglomeration and poor dispersion during photodeposition. Finely dispersed Pt NPs (2-4 nm, 53% dispersion) successfully competed with shallow/deep trap states and drove the photogenerated electrons to active metallic sites in a drastically reduced time period as investigated by femtosecond transient absorption spectroscopy. Typically, an interfacial electron transfer rate, KIET,avg, of 2.5 × 1010 s-1 was observed for Pt/CN, while 0.087 × 1010 s-1 was observed in Au/CN. Band alignment/potentials at M/CN Schottky junctions were derived and most favorable in Pt/CN with CB tail states much above the water reduction potential; however, in the case of Pd, these extend much below the H+/H2 potential and hence behave like deep trap states. Thus, in Pd/CN (τ0 = 4200 ps, 49%) and Ag/CN (3870 ps, 53%), electron deep trapping dominates over charge transfer to active sites. The present study will help in designing futuristic new cocatalyst-photocatalyst systems.

Hierarchical 3D Flower-like Metal Oxides Micro/Nanostructures: Fabrication, Surface Modification, Their Crucial Role in Environmental Decontamination, Mechanistic Insights, and Future Perspectives.

Hierarchical micro/nanostructures are constructed by micro-scaled objects with nanoarchitectures belonging to an interesting class of crystalline materials that has significant applications in diverse fields. Featured with a large surface-to-volume ratio, facile mass transportation, high stability against aggregation, structurally enhanced adsorption, and catalytical performances, three dimenisional (3D) hierarchical metal oxides have been considered as versatile functional materials for waste-water treatment. Due to the ineffectiveness of traditional water purification protocols for reclamation of water, lately, the use of hierarchical metal oxides has emerged as an appealing platform for the remediation of water pollution owing to their fascinating and tailorable physiochemical properties. The present review highlights various approaches to the tunable synthesis of hierarchical structures along with their surface modification strategies to enhance their efficiencies for the removal of different noxious substances. Besides, their applications for the eradication of organic and inorganic contaminants have been discussed comprehensively with their plausible mechanistic pathways. Finally, overlooked aspects in this field as well as the major roadblocks to the implementation of these metal oxide architectures for large-scale treatment of wastewater are provided here. Moreover, the potential ways to tackle these issues are also presented which may be useful for the transformation of current water treatment technologies.

Effects of Heterologous Bovine Seminal Plasma-Supplemented Egg Yolk-Based Extender on Cryosurvivability of Pantja Buck Semen.

The present study was conducted to observe the effects of removal of seminal plasma of Pantja buck semen and supplementation of bovine seminal plasma (BSP) in the extender before cryopreservation. In a preliminary experiment, different levels of BSP were supplemented (1, 3, 5, 7, and 9% v/v) in egg yolk (7.5% egg yolk)-tris (EYT) extender and used for cryopreservation of Pantja buck semen. Results in terms of motility, viability, plasma membrane integrity, acrosome integrity, and lipid peroxidation showed that 5% BSP was suitable for maintaining Pantja buck semen quality during cryopreservation. In the final experiment, pooled semen from four Pantja bucks was split into three aliquots (I, II, and III). Aliquot I was directly diluted in EYT extender and grouped as the control (C); aliquot II and III were washed separately with TALP solution and diluted as D1 (Washed semen with EYT extender) and D2 (Washed semen with EYT extender containing 5% BSP), respectively. Seminal attributes (sperm individual motility, viability, plasma membrane integrity, acrosome integrity, and total morphological abnormalities) were assessed at the postdilution, postequilibration, and post-thawing stages. Alanine aminotransferase (ALT), aspartate aminotransferase (AST), malondialdehyde (MDA) concentration, and glutathione peroxidase (GSH-Px) activity were measured at post-thaw. Washed semen significantly improved (p < 0.05) seminal parameters at post-thaw compared with unwashed semen (control). A significant difference (p < 0.05) was observed in seminal attributes between freezing stages and between dilution groups. Significantly higher (p < 0.05) post-thaw sperm motility, viability, plasma membrane integrity, acrosome integrity, and GSH-Px activity, and significantly lower (p < 0.05) MDA concentration and extracellular release of enzymes (ALT, AST) were observed in group D2 compared with control and D1. The results of the present study demonstrated that cryopreservation of washed Pantja buck semen diluted with 5% BSP-supplemented EYT extender can improve post-thaw semen quality.

Green fodder cultivation improves technical efficiency of dairy farmers in semi-arid tropics of central India: a micro-analysis.

This study assessed the impact of improved green fodder production activities on technical efficiency (TE) of dairy farmers in climate vulnerable landscapes of central India. We estimated stochastic production frontiers, considering potential self-selection bias stemming from both observable and unobservable factors in adoption of fodder interventions at farm level. The empirical results show that TE for treated group ranges from 0.55 to 0.59 and that for control ranges from 0.41 to 0.48, depending on how biases are controlled. Additionally, the efficiency levels of both adopters and non-adopters would be underestimated if the selectivity bias is not appropriately accounted. As the average TE is consistently higher for adopter farmers than the control group, promoting improved fodder cultivation would increase input use efficiency, especially in resource-deprived small holder dairy farmers in the semi-arid tropics.

Exploration of urinary metabolite dynamicity for early detection of pregnancy in water buffaloes.

Early and precise pregnancy diagnosis can reduce the calving interval by minimizing postpartum period. The present study explored the differential urinary metabolites between pregnant and non-pregnant Murrah buffaloes (Bubalus bubalis) during early gestation to identify potential pregnancy detection biomarkers. Urine samples were collected on day 0, 10, 18, 35 and 42 of gestation from the pregnant (n = 6) and on day 0, 10 and 18 post-insemination from the non-pregnant (n = 6) animals. 1H-NMR-based untargeted metabolomics followed by multivariate analysis initially identified twenty-four differentially expressed metabolites, among them 3-Hydroxykynurenine, Anthranilate, Tyrosine and 5-Hydroxytryptophan depicted consistent trends and matched the selection criteria of potential biomarkers. Predictive ability of these individual biomarkers through ROC curve analyses yielded AUC values of 0.6-0.8. Subsequently, a logistic regression model was constructed using the most suitable metabolite combination to improve diagnostic accuracy. The combination of Anthranilate, 3-Hydroxykynurenine, and Tyrosine yielded the best AUC value of 0.804. Aromatic amino acid biosynthesis, Tryptophan metabolism, Phenylalanine and Tyrosine metabolism were identified as potential pathway modulations during early gestation. The identified biomarkers were either precursors or products of these metabolic pathways, thus justifying their relevance. The study facilitates precise non-invassive urinary metabolite-based pen-side early pregnancy diagnostics in buffaloes, eminently before 21 days post-insemination.

Development of heterogeneous photocatalysts via the covalent grafting of metal complexes on various solid supports.

To date, remarkable progress has been achieved in the development of photocatalysts owing to their high activity, selectivity, and tunable light absorption in the visible light range. Recently, heterogeneous photocatalytic systems have emerged as potential candidates due to their beneficial attributes (e.g., high surface area, ease of functionalization and facile separation). Herein, we provide a concise overview of the rational design of heterogeneous photocatalysts by grafting photoactive complexes on heterogeneous support matrices via covalent grafting and their detailed characterization techniques, which have been followed by the landmark examples of their applications. Also, major challenges and opportunities in the forthcoming progress of these appealing areas are emphasised.

Investigation of Li-rich manganese oxide spinel structures for electrochemical water oxidation catalysis.

The rapid development of efficient and cost-effective catalysts is essential for the oxygen evolution reaction. Herein, nanostructured spinels LiMn2O4, delithiated λ-MnO2, and Li4Mn5O12 have been synthesized at low temperatures and are investigated as electrocatalysts for alkaline water oxidation reactions. Among the nanostructured spinels, LiMn2O4, delithiated λ-MnO2, and Li4Mn5O12, the former spinel which is classical LiMn2O4 with 1/6th of the Mn replaced by Li outperforms for the OER that shows a current density of 5 mA cm-2 at a lowest overpotential of 430 mV and Tafel slope of 74 mV per decade. Electrochemical impedance studies revealed the least value of charge transfer resistance of the Li4Mn5O12 spinel and suggest fast reaction kinetics for the oxygen evolution reaction as compared to other spinels. The XPS and TEM of Li4Mn5O12, recorded after a 12-hour stability test for oxygen evolution activity, confirm that the oxidation state of Mn and the morphology of Li4Mn5O12 remain intact even after the electrocatalytic reaction, however, it undergoes amorphization. The higher activity of Li4Mn5O12 synthesized in the present work is attributed to the low temperature synthesis resulting in the formation of a nanostructured Li rich spinel with a high surface area, along with an increased percentage of ionic bonding and the presence of 3D Li diffusion channels. The role of Li was further supported by XPS studies that revealed a shift in Li 1s binding energy as well as quantitative reduction relative to Mn for Li4Mn5O12 after a long term test.

An Anatomical Evaluation of Normal and Aberrant Foramen Ovale in Skull Base with Its Clinical Significance.

Introduction: Foramen ovale is one of the most significant foramina of skull base and transmits mandibular nerve. Its detailed knowledge is crucial in treatment of trigeminal neuralgia and various diagnostic practices. Aim: Aim of the study was to provide anatomical data of foramen ovale regarding number, shape, diameters and its relation to nearby bony landmarks. Material and method: The present study was ethically approved and 100 dry adult human skulls were included in the study to evaluate 200 foramina ovale. Non-metric parameters were observed and metric parameters were measured with Vernier calliper and goniometer. Results:Different kinds of shapes were found in foramen ovale. Variant features in the form of bony spine, ridge, foramen or bar were identified. The means of anteroposterior and transverse diameter of foramen ovale were found to be 8.16 and 4.97 mm on the right side, and 7.68 and 4.74 mm on the left side. The mean distance of its anterior and posterior ends from the midsagittal plane were 22.69 and 28.92 mm on the right side, and 22.18 and 22.66 mm on the left side. Distance from the lateral border of foramen ovale to the posterior end of zygoma and midpoint of infratemporal crest was found to be 30.65 and 21.05 mm on the right, and 30.30 and 20.87 mm on the left side. The mean of angle of foramen ovale with midsagittal was 45.44º on the right side and 45.78º on the left side. Conclusion:Variations found in foramen ovale are key points to keep in mind while operating in this region. Measured metric parameters were found to a higher extent on the right side than the left one. The present study will be helpful for both further research and neurosurgeons operating in this region.

Changes in surface morphology, lectin staining, and gene expression of caprine endometrium exposed to estradiol, progesterone, and mifepristone in vitro.

Background: In mammalian females, the uterine tissue is highly responsive to steroid hormones and their antagonists. Aims: In the present study, topographical, histoarchitectural, and gene expression changes in goat endometrium treated with estradiol, progesterone, and mifepristone for 24 h were investigated, in vitro. Methods: Scanning electron microscopy (SEM) was used for surface topographical analysis; WGA and DBA lectins were used for histochemical analysis; and qRT-PCR was done for the quantification of mRNA levels of MKI67 (marker of proliferation Ki67), ESR1 (estrogen receptor), PGR (progesterone receptor), CASP3 (caspase 3), and PDGFR-ß (platelet derived growth factor receptor-ß). Results: Few topographical alterations were observed in endometrial glands and the presence of scattered mucoid granules. A significant decline in WGA staining was reported only in the progesterone group. However, DBA binding was highest in the progesterone group and lowest in the mifepristone group. The expression of MKI67 gene declined to 79% in the mifepristone group, while in the estradiol and progesterone groups it elevated to 153% and 41%, respectively, than control; a similar trend was observed for PDGFR-ß. The mRNA abundance for ESR1 declined to 59% in the progesterone group and 10% in the mifepristone group. However, a 100% increase occurred in the estradiol group. PGR expression followed the same trend as that of ESR1. CASP3 declined in the estradiol (50%) and progesterone (37%) group, but it showed a 67% increase in the mifepristone group. Conclusion: We concluded that the caprine uterus undergoes dramatic alteration in structure and functions in response to different kinds of steroidal environments.

Impact of plasma glucose and duration of type 2 diabetes mellitus on SYNTAX Score II in patients suffering from non ST-elevation myocardial infarction.

Aim    The objective was to assess the correlation of fasting plasma glucose (FPG), HbA1c, and the duration of type 2 diabetes mellitus (T2DM) with SYNTAX score (SS) II in patients with non-ST elevation myocardial infarction (NSTEMI).Material and methods    FPG and HbA1C were measured in 398 patients presenting with NSTEMI at admission. SS II was calculated using an online calculator. Patients were stratified according to SS II (≤21.5, 21.5-30.6, and ≥30.6), defined as SS II low, mid, and high, respectively.Results    37.7 % of subjects were diabetic. Correlations of FPG (R=0.402, R2=0.162, p<0.001) and HbA1c (R=0.359, R2=0.129, p<0.001) with SS II were weak in the overall population. Duration of T2DM showed very strong correlation with SS II (R=0.827, R2=0.347). For the prediction of high SS II in the study population, FPG≥98.5 mg / dl demonstrated a sensitivity of 58 % and a specificity of 60 %, and HbA1c ≥6.05 demonstrated a sensitivity of 63 % and a specificity of 69 %. Duration of T2DM (adjusted odds ratio (OR): 1.182; 95 % confidence interval (CI): 1.185-2.773) and FPG (OR: 0.987; 95 % CI: 0.976-0.9959) were significantly associated with high SS II after controlling for other risk factors. Duration of T2DM (Beta=0.439) contributed strongly to variance of SS II, whereas HbA1c (Beta=0.063) contributed weakly.Conclusion    Duration of T2DM is a very important risk factor for severity of coronary artery disease.

Pattern of Male Hypogonadism and Outcome of Treatment in South Rajasthan.

Male reproductive functions are governed by hypothalamic pituitary testicular axis. If any component of this axis malfunctions, then hypogonadism will develop which is characterized by ill-defined secondary sexual features and low serum testosterone. The common patterns seen are primary and secondary testicular failure in the young; and late onset hypogonadism in the elderly. All such cases can be virilized and managed by androgen supplementation. Spermatogenesis can be induced by use of appropriate gonadotropins in selected cases. The aim of the study was to find out the pattern, management and outcome of male hypogonadism. MATERIAL: It was a prospective questionnaire based observational study, carried out on infertile hypogonadic males, attending medicine outdoor at medical college hospital from January 2015 to December 2020. There were 50 males with hypogonadic features, cases of late onset of hypogonadism were excluded. Sexual maturity rating, semen analysis, serum testosterone and FSH level were estimated in all patients at baseline and at 6 months duration of treatment. Testicular biopsy, Karyotyping and MRI brain were performed in selected cases. Azoospermic patients having hypogonadotropic hypogonadism were treated with long-acting testosterones and gonadotropins. OBSERVATION: The study subjects were infertile azoospermic males. On the basis of serum FSH and testosterone levels, they were classified into two groups. Group A (n=42) cases were hypergonadotropic hypogonadism or primary testicular failure; of these 32 were Klinefelter syndrome (XXY), 7 chronic orchitis and 3 empty scrotal syndrome including one case of anorchia. These patients also developed other systemic illnesses in addition to hypogonadism. Group B (n=8) hypogonadotropic hypogonadism or secondary testicular failure; of these 2 were Kallman syndrome and the rest were idiopathic. After testosterone replacement all patients were virilized and there was marked improvement in libido and androgenization. CONCLUSION: The study brings out that primary testicular failure is more common than secondary testicular failure. Both pattern of hypogonadism should receive lifelong androgen replacement therapy; otherwise, they will be a basket of multiple systemic disorders. Presently testosterone undecanoate once in every three months is the agent of choice.

An Earth-abundant cobalt based photocatalyst: visible light induced direct (het)arene C-H arylation and CO2 capture.

In this work, we have reported a noble metal free heterogeneous photocatalyst to carry out direct (het)arene C-H arylation and solvent-free CO2 capture via single-electron transfer processes at room temperature and under pressure. The catalytic system comprises a cobalt(III) complex grafted over the silica coated magnetic support for the efficient recovery of the photocatalytic moiety without hampering its light-harvesting capability. The novel Earth-abundant cobalt(III) based photocatalyst possesses various fascinating properties such as high surface area to volume ratios, large pore volume, crystalline behaviour, high metal loading, excellent stability and reusability. The general efficacy of the highly abundant and low-cost cobalt based heterogeneous nanocatalyst was checked for the selective conversion of aryldiazonium salts into synthetically and pharmaceutically significant biaryl motifs under ambient conditions upon irradiation with visible light. The highly efficient photocatalytic conversion of carbon dioxide (CO2) to a value-added chemical was accomplished under mild reaction conditions with high selectivity, showing the added benefit of operational simplicity.

Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL): a good practice guide, pictorial review, and new perspectives.

Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is a rare but emerging T-cell non-Hodgkin lymphoma. It has two distinct subtypes, "effusion-only" or "mass-forming" disease, arising around implants in patients with in situ or previous history of textured-surface breast implants. The clinical, histopathological and imaging features are unique and nuanced as compared to primary breast malignancy and other lymphoma categories. Prompt recognition and diagnosis triggers referral to appropriate BIA-ALCL centres and initiation of treatment, with potential for excellent prognosis. Definitive management of both subtypes involves implant and capsule removal; systemic therapy is reserved for mass-forming disease and advanced-stage disease. There have been recent crucial advances in the diagnostic pathway, with publication of national and international guidelines: from the UK Medicines Healthcare products Regulatory Agency (MHRA) Plastic, Reconstructive and Aesthetic Surgery Expert Advisory Group (PRASEAG), and the United States National Comprehensive Cancer Network (NCCN). This review provides a practical guide to the clinical work-up of BIA-ALCL, enabling optimisation of the diagnostic imaging pathway, with representative cases.

g-C3N4/Ca2Fe2O5 heterostructures for enhanced photocatalytic degradation of organic effluents under sunlight.

g-C3N4/Ca2Fe2O5 heterostructures were successfully prepared by incorporating g-C3N4 into Ca2Fe2O5 (CFO). As prepared g-C3N4/CFO heterostructures were initially utilized to photodegrade organic effluent Methylene blue (MB) for optimization of photodegradation performance. 50% g-C3N4 content in CFO composition showed an enhanced photodegradation efficiency (~ 96%) over g-C3N4 (48.15%) and CFO (81.9%) due to mitigation of recombination of photogenerated charge carriers by Type-II heterojunction. The optimized composition of heterostructure was further tested for degradation of Bisphenol-A (BPA) under direct sunlight, exhibiting enhanced photodegradation efficiency of about 63.1% over g-C3N4 (17%) and CFO (45.1%). The photoelectrochemical studies at various potentials with and without light illumination showed significant improvement in photocurrent response for g-C3N4/Ca2Fe2O5 heterostructures (~ 1.9 mA) over CFO (~ 67.4 µA). These studies revealed efficient solar energy harvesting ability of g-C3N4/Ca2Fe2O5 heterostructures to be utilized for organic effluent treatment.

Spent marigold flower meal as an alternate feed for goats.

This research trial is aimed to study the nutritional qualities and significance of feeding spent marigold flower meal (SMFM) in goats. SMFM and diet containing iso-nitrogenous concentrate mixture with different levels of spent marigold flower meal (0-30%) were studied for in vitro degradation. Depending upon the in vitro results, concentrate mixture containing 15% level of SMFM was selected for in vivo trial. In vivo studies were conducted for a period of 60 days, and 12 local, non-descript, adult male goats (10-14 months age; 31.09 ± 2.91 kg body weight) were randomly assigned to two groups and were fed on ad libitum wheat straw with either conventional (control) or SMFM containing concentrate mixture (treatment). Results of the study showed that there was no variation in body weight of the goats between periods and between groups. DM and OM intake along with their digestibility were similar among the two groups. The digestibility of all other nutrients was comparable between the two groups. Nitrogen, calcium and phosphorus balance were positive in both the groups without any significant disparity. Moreover, experimental goats did not differ in biochemical parameters, without any significant difference between periods and dietary treatments except AST level which was significantly higher (P > 0.05) in treatment group. So, this study successfully demonstrates that SMFM could be incorporated in the concentrate mixture, up to 15% without any discernable difference in the performance of goats.

Chronic lymphocytic leukaemia and Richter's transformation: multimodal review and new imaging paradigms.

Chronic lymphocytic leukaemia (CLL) is the most common leukaemia in adults. It is a malignancy of CD5 B-cells characterised by small, mature-appearing lymphocytes accumulating in the blood, bone marrow, and lymphoid tissues. Richer transformation (RT) is an important adverse complication. Detection of RT is critical to allow initiation of appropriate therapy. CLL staging and response evaluation is complicated and nuanced. From our extensive tertiary centre experience of several hundred CLL cases over the last decade, we detail key computed tomography (CT) and positron-emission tomography (PET) imaging features of the natural history of CLL. The authors present an original imaging-based patient-management paradigm for the investigation of potential RT, which will inform global practice. Potential applications of whole-body diffusion weighted imaging, novel PET radiotracers, minimal residual disease, and ct-DNA are addressed.
