Evaluation of biological selenium nanoparticles on growth performance, histopathology of vital organs and genotoxicity in Japanese quails (coturnix coturnix japonica).

Research on the effects of selenium nanoparticles (Se-NPs), particularly in Japanese quails, is lacking, especially regarding the potential for DNA damage. Therefore, this study aimed to investigate the impact of administering 0.2 and 0.4 mg/kg of Se-NPs on the growth performance, DNA integrity, and histopathological alterations of the liver, lung, kidney, and heart in quails. A total of 480 one-day-old Japanese quails were divided into three experimental groups as follows: Group 1 served as the control and received only basic feed, while Group 2 and 3 received 0.2 mg/kg and 0.4 mg/kg of Se-NPs via oral gavage. Our results suggested that, birds fed with Se-NPs at both levels significantly (p < .01) reduced feed intake, however, weight gain was significantly (p < .01) increased in quails supplemented with 0.2 mg/kg. Similarly, feed conversion ratio (FCR) was significantly (p < .01) reduced in group supplemented with 0.2 mg/kg Se-NPs. White blood cells increased significantly (P0.01) in 0.4 mg/kg while haemoglobin and red cell distribution width decreased (p < .01) in the same group. Both treatment regimens resulted in DNA damage and histopathological alterations; however, the adverse effects were more prominent in the group receiving the higher dose of 0.4 mg/kg. These findings indicate that the lower dose of 0.2 mg/kg may have beneficial effects on growth. However, the higher dose of 0.4 mg/kg not only negatively impacts growth but also leads to histopathological alterations in major organs of the body and DNA damage as well.

Interaction of blood calcium with milk yield, energy metabolites, subclinical mastitis, and reproductive performance in crossbred dairy cows.

Limited literature is available on the consequences of postpartum low blood calcium (Ca) concentration in crossbred cows. The research aimed to investigate the correlation between postpartum serum Ca levels and various parameters, including milk yield, serum energy metabolites, milk somatic cell count, and reproductive factors in crossbred cows. Following parturition, a total of 45 potential high-yielding F2 (HF × Sahiwal; Genotype: 75:25) dairy cows were enrolled . These cows were categorized based on plasma calcium concentrations into three groups: a low calcium group (Ca-L) with a calcium concentration of <5 mg/dL, a medium calcium group (Ca-M) with a calcium concentration ranging from 5 to 8.5 mg/dL, and a high calcium group (Ca-H) with a calcium concentration exceeding 8.5 mg/dL. The study parameters were measured over an 8-week period. The results indicated that overall milk yield and blood glucose were significantly higher in the Ca-H group compared to Ca-M and Ca-L (p < .01). Blood cholesterol was significantly higher in Ca-M (p < .01), while blood triglyceride was significantly lower in both Ca-M and Ca-H. Overall, blood cortisol did not show a significant change between these groups (p < .01); however, progesterone levels were higher (p < .01) in Ca-M and Ca-H cows. Furthermore, somatic cell count (SCC) significantly (p < .01) decreased in cows with Ca-H compared to Ca-L. Additionally, postpartum oestrous interval and interestrus interval decreased significantly (p < .01) in Ca-M and Ca-H compared to Ca-L. These findings suggest that cows with blood calcium levels exceeding 8.5 mg/dL exhibited significantly higher milk yield, blood metabolite levels, a lower likelihood of subclinical mastitis, and earlier reproductive activity after calving.

Impact of coriander (Coriandrum sativum), garlic (Allium sativum), fenugreek (Trigonella foenum-graecum) on zootechnical performance, carcass quality, blood metabolites and nutrient digestibility in broilers chickens.

The study investigated the impact of incorporating a specific herbal blend comprising coriander, garlic, and fenugreek (CGF) at various levels on the zootechnical performance, blood metabolites and nutrient digestibility in broiler chickens. The 42-day experiment involved 360 broilers (Cobb 500), organized into four distinct treatment groups. The dietary interventions included a control group consisting of a basal diet and the same diet was supplemented with CGF at rates of 1, 2, and 3%. Broilers receiving a 1% phytogenic mixture exhibited significantly increased live weight and carcass weight. Moreover, the digestibility of crude protein and crude fat significantly improved in broilers supplemented with a 1% phytogenic mixture. On the other hand, the digestibility of calcium and phosphorus showed a notable increase in broilers fed with a 3% phytogenic mixture. Regarding serum metabolites, the 1% phytogenic mixture group displayed significantly higher levels of high density lipoprotein and triglycerides. The supplementation of the broiler diet with a herbal mixture of coriander, fenugreek, and garlic at a 1% rate resulted in improved growth performance, carcass quality, nutrient digestion, and lipid profile.

Effects of zinc supplementation from organic and inorganic sources on growth, blood biochemical indices, and intestinal microarchitecture in broilers.

In poultry nutrition, zinc supplementation is typically achieved through the addition of zinc oxide or zinc sulfate to the feed. The alternative approach of organic sources utilizes an organic ligand to bind zinc (Zn), resulting in higher bioavailability. Thus, a study was conducted to assess and compare the impact of a methionine-complexed Zn versus an inorganic Zn on growth, blood biochemical profile, gut histomorphology, and fecal excretion of Zn in broilers. The experimental design included two treatments: the addition of a zinc amino acid complex or zinc oxide to the basal diet. The zinc amino acid complex was supplemented at a dose equivalent to the inorganic zinc (Zn-80), while the organic zinc was provided at levels of 20, 40, and 80 mg/kg to a total of 400 broilers. There were five treatments in total, and each treatment was replicated four times. Broilers supplemented with an organic form of Zn at the level of 80 mg/kg had significantly (p < 0.05) higher body weight gain and lower feed conversion ratio (F/G). Significantly (p < 0.05) higher Zn excretion was recorded in broilers supplemented with inorganic Zn supplementation. Significantly (p < 0.05) higher villus length and width, their ratio, and lower (p < 0.05) crypt depth were observed in birds supplemented with 80 mg/kg organic Zn. From the results of the present study, it was concluded that Zn from an organic source at the rate of 80 mg/kg was superior in terms of growth performance, intestinal histomorphology and less excretion of Zn to the environment in broilers.

Evaluation of blood minerals and oxidative stress changing pattern in prepartum and postpartum Achai and Holstein Friesian dairy cows.

This research focused on evaluating blood mineral levels and malondialdehyde (MDA) as an indicator of oxidative stress before and after giving birth in Achai and Holstein Friesian (HF) dairy cows. Blood samples were obtained from a total of 50 cows representing both breeds on the third, second, and first week prior to calving, as well as on the day of calving (day 0). Subsequently, samples were collected on the 1-3 weeks postpartum to allow a comprehensive evaluation of blood parameters throughout the peripartum period. Results showed a significant (p < .01) decrease in serum zinc (Zn) levels on the day of parturition in both breeds. Additionally, HF cows exhibited higher (p < .01) Zn levels on week 2 before giving birth. Interestingly, blood selenium (Se) concentration increased (p < .01) in HF cows on weeks 2 and 3 after calving. In contrast, Achai cows showed a rise (p < .01) in blood Se on week 3 of parturition. Blood copper (Cu) levels were higher (p < .01) on weeks 2 and 3 after parturition in HF cows and on third week before parturition compared to Achai cows, where serum Cu remained high on week 1 of parturition. The findings indicated that blood magnesium (Mg) was higher (p < .01) on third week before parturition in Achai cows and on weeks 2 and 3 after parturition. Serum calcium (Ca) was higher (p < .01) in both HF and Achai cows on weeks 2 and 3 after parturition, and lower (p < .01) on third week before giving birth in both breeds. The mean blood MDA levels in Achai cows were lower (p < .01) on weeks 1 to 3 postpartum or 3 weeks before giving birth. In HF cows, serum MDA increased (p < .01) just before 2 weeks of parturition and remained elevated until 3 weeks of parturition. Thus, both breeds exhibited a similar pattern of mineral fluctuations; yet, Achai cows demonstrated greater resilience to oxidative stress compared to HF cows during the transition period.

Ameliorative Effect of Pomegranate Peel Powder on the Growth Indices, Oocysts Shedding, and Intestinal Health of Broilers under an Experimentally Induced Coccidiosis Condition.

Coccidiosis stands as one of the most prevalent enteric parasitic diseases in broilers. While antibiotics have traditionally been used for the control of coccidiosis, concerns related to drug residues and the emergence of resistance in chickens have prompted consumer apprehensions. In this study, 600 Ross 308 broiler chicks were randomly divided into five groups: a control group without specific treatments (NC), broilers deliberately exposed to Eimeria tenella (positive control), broilers challenged with E. tenella but dosed with antibiotics (AT), and two groups experimentally exposed to E. tenella while simultaneously receiving pomegranate peel powder (PPE) at dosages of 3 g/kg (3PPP) and 6 g/kg (6PPP). The results revealed that all Eimeria-treated birds exhibited significantly worse growth performance compared to the NC. Notably, a marked improvement was observed in birds infected with E. tenella when supplemented with 6PPP. Both 3PPP and 6PPP supplementation significantly reduced lesion scores, mortality, and oocysts per gram (OPG). Furthermore, histological examination of the cecum indicated that the villus dimensions were restored by PPP supplementation in infected birds. In conclusion, Eimeria-infected birds supplemented with 6PPP experienced an enhanced growth rate, lowered lesion scores, alleviated oocyst shedding, and improved intestinal histological dimensions.

Dietary Oyster Mushroom (Pleurotus ostreatus) Waste Inhibits Experimentally Induced Eimeria tenella Challenge in Japanese Quails Model.

The aim of this study was to investigate the potential of dietary 3% oyster mushroom (Pleurotus ostreatus) waste in enhancing the anticoccidial effects in broilers challenged with Eimeria tenella infection. The experiment involved a total of 600 Japanese quails, raised from one to thirty-five days of age, which were divided into four treatment groups. These included a negative control group that received a basal diet (BD) without any anticoccidial or antibiotic supplementation in the non-challenged birds (negative control, NC); a positive control (PC) group consisting of NC birds challenged with E. tenella; a group that received the BD with an anticoccidial drug (standard); and a group that received the BD supplemented with 3% waste from oyster mushrooms (3% Pleurotus ostreatus). The results showed that the feed intake, body weight gain, and feed efficiency were significantly lower in the PC (p < 0.05). However, the growth traits were similar in the standard and 3% Pleurotus ostreatus-treated groups. Similarly, there was no difference (p < 0.05) in the mortality rate, oocyst count in the feces, and lesion score between the standard and 3% Pleurotus ostreatus groups. Based on intestinal histology evaluation, the villi height and width were significantly higher in the standard and 3% Pleurotus ostreatus-treated groups compared to those of the PC (p < 0.01). In conclusion, it was found that 3% Pleurotus ostreatus effectively mitigated the low growth rate of Japanese quails induced by coccidial infection.

Effect of Lemon (Citrus limon, L.) Peel Powder on Oocyst Shedding, Intestinal Health, and Performance of Broilers Exposed to E. tenella Challenge.

To date, no study has reported the anticoccidial effect of lemon peel powder in broilers. Coccidiosis, caused by Eimeria species, is the prevalent enteric parasitic disease in poultry. Although certain chemical drugs have been used for their control, concerns regarding drug residues and the development of resistance in chickens have arisen among consumers. In this study, a total of 300 Ross 308 broiler chicks were randomly allocated into five groups (five equal replicates of 12 animals). The first group served as the control and did not receive any specific treatment (NC). The second group, referred to as the positive control (PC) group, was deliberately exposed to Eimeria tenella. The third group was challenged with E. tenella and also received treatment with amprolium (1 g/kg) and was designated as AT. The fourth and fifth groups were challenged with E. tenella and simultaneously supplemented with lemon peel powder at a dosage of 3 g/kg (LPP3) and 6 g/kg (LPP6). Sporulated E. tenella oocysts (5 × 104/mL bird) on day 22 of the experiment were administered to the infected broiler chickens. The results indicated that in comparison with the NC, all Eimeria-treated birds exhibited significantly (p < 0.05) lower growth performance. However, a notable improvement was observed when infected birds also received a supplement of LPP3 and LPP6 in their feed. Both LPP3 and LPP6 supplementation significantly (p < 0.05) reduced mortality, lesion scores, and oocyst per gram (OPG) of feces compared with the PC group. Additionally, the histological features of the cecum revealed that villus height, villus width, and crypt depth were partially restored under supplementation with LPP3 and LPP6 in the infected birds. Overall, the results demonstrate that Eimeria-infected birds supplemented with LPP3 and LPP6 exhibited improved growth performance, reduced OPG, lowered intestinal coccidiosis lesion scores, and enhanced intestinal histological features.

Curcumin Co-Encapsulation Potentiates Anti-Arthritic Efficacy of Meloxicam Biodegradable Nanoparticles in Adjuvant-Induced Arthritis Animal Model.

This study aimed to evaluate the anti-arthritic activity of curcumin and meloxicam co-loaded PLGA nanoparticles in adjuvant-induced arthritic rats. PLGA nanoparticles encapsulating curcumin (nCur) and meloxicam (nMlx) alone and in combination (nCur/Mlx) were used to characterize zeta size and potential, polydispersity index, encapsulation efficiency (%), compound-polymer interactions (FT-IR analysis), and surface morphology (SEM imaging). In vivo, Complete Freund's adjuvant-induced arthritic rats were intraperitoneally (i.p.) administered with curcumin, meloxicam, curcumin plus meloxicam, nCur, nMlx, and nCur/Mlx for 28 consecutive days. Results showed that nCur, nMlx, and nCur/Mlx significantly (p ≤ 0.05) reduced paw swelling and arthritic score, restored body weight and the immune organ index (thymus and spleen), as well as attenuated serum inflammatory markers (RF, CRP, and PGE2) and oxidative stress parameters (MDA, SOD, and CAT) in adjuvant-induced arthritic rats compared to free compounds. In addition, mono- and dual-compound-loaded nanoparticles significantly (p ≤ 0.05) down-regulated pro-inflammatory cytokines (TNF-α, IL-1ß, and IL-6), up-regulated anti-inflammatory cytokines (IL-4, IL-10, and IFN-γ), and modulated OPG and RANKL expressions in paw tissue. The aforementioned results were further confirmed through radiological and histopathological examinations. Furthermore, the anti-arthritic effect of nCur/Mlx was notably (p ≤ 0.05) enhanced compared to nCur or nMlx alone. In conclusion, the co-nanoencapsulation of curcumin could potentiate the anti-arthritic activity of meloxicam and could provide a novel therapeutic approach for the formulation of nanocarrier pharmaceutical products for the management of arthritis.

Blood metabolic pattern and somatic cells dynamic in Achai and Holstein Friesian cows during transition period.

This study focused on assessing blood metabolites and somatic cell count (SCC) during the transition period in Achai and Holstein Friesian cows. Blood samples were collected from cows of both breeds on days -21, -14, -7 (pre-partum period), on day 0 (parturition day) and then on days 7, 14 and 21 (post-partum period). Additionally, milk samples were obtained on the day of parturition and on days 7, 14 and 21 post-partum for SCC assessment. Among Holstein cows, blood glucose levels showed a significant increase on day -21 before calving, and a decrease on the 14th and 21st days post-partum. Similarly, the blood triglycerides concentration exhibited a significant rise in Holstein cows 21 days before calving, while Achai cows experienced a significant decline in blood triglycerides on the day of parturition and throughout the entire post-partum period. Comparing Holstein and Achai cows, blood cholesterol was significantly higher in Holstein cows on day -21 before calving, whereas Achai cows had significantly lower blood cholesterol levels on the day of parturition. Regarding blood protein, Holstein cows exhibited significantly higher levels on day 14 post-partum, while Achai cows had lower protein levels 7 days before calving. The results further demonstrated that SCC was significantly elevated in Holstein cows on day 21 of parturition and lower on the day of parturition in Achai cows. Overall, the metabolic profile trend and SCC were comparable, yet the studied parameters were more pronounced in Holstein Friesian compared to Achai cows.

Impact of grape (Vitis vinifera) seed extract on egg production traits, nutrients digestability, lipid peroxidation and fertility of golden laying hens (Gallus gallus) during early stage of production.

Grape by-products represent outstanding alternatives to replace conventional and unsustainable feed sources, given the substantial quantities generated annually by the winery industry. Regrettably, the majority of these by-products are wasted, resulting in significant environmental and economic repercussions. This study was conducted to assess the growth performance, feed efficiency, egg production and quality, lipid peroxidation, fertility and hatchability of reproductive laying hens during their early production stage. A total of 720 golden laying hens, all approximately 25 weeks old and with similar body weights, were randomly assigned to four experimental treatments (six replicates) as follows: control group receiving only the standard diet, (2) a group receiving the standard diet supplemented with grape seed extract at a rate of 250 g/kg (GSE1), (3) a group receiving the standarddiet supplemented with grape seed extract at a rate of 500 g/kg (GSE2), and (4) a group receiving the standarddiet supplemented with grape seed extract at a rate of 750 g/kg (GSE3). There were no significant change (p > 0.05) in feed intak, body weight gain and feed conversion ratio between the control and the experimental groups. Egg weight, egg shell thickness and egg shell weight were significantly (p < 0.05) higher in GSE250 GSE500 and GSE750 compared to the control. The results showed that hen day egg production was also significantly higher (p < 0.05) in GSE500 and GSE 750 compared to the control. Fertility level of GSE 500 and GSE750 was significantly (p < 0.5) higher compared to the control. The MDA level decreased significantly (p < 0.05) in the GSE supplemented birds compared to the control. From these findings, we concluded that GSE 750 had positive impact on egg production, reducing lipid peroxidation and improving fertility in golden laying hens.

Anti-Pyretic, Analgesic, and Anti-Inflammatory Activities of Meloxicam and Curcumin Co-Encapsulated PLGA Nanoparticles in Acute Experimental Models.

Herein, we evaluated the in vivo effects of meloxicam and curcumin co-encapsulated PLGA nanoparticles in experimental acute models of pyrexia, nociception, and inflammation. Seven groups (n = 6) were designed for each investigation and pretreated intraperitoneally (i.p.): the control group, meloxicam (4 mg/kg b.w.), curcumin (15 mg/kg b.w.), and equivalent content containing PLGA capped nanoparticles of meloxicam (Mlx-NP) and curcumin (Cur-NP) alone and in combination (Mlx-Cur-NP; at two doses). The results showed that PLGA encapsulation significantly (p ≤ 0.05) improved the in vivo activities of each compound. Furthermore, co-encapsulation of meloxicam and curcumin potentiated the anti-pyretic effect on yeast-induced pyretic rats, anti-nociceptive effect on nociception induced in rats by formalin and heat, and anti-edematogenic activity in xylene-induced ear edema in rats in a dose-dependent manner. In carrageenan-induced paw inflammation in rats, meloxicam and curcumin co-loading (Mlx-Cur-NP) resulted in significant (p ≤ 0.05) inhibition of paw inflammation, reduction in TNF-α and PGE2 levels, downregulation of expressions of pro-inflammatory cytokines (TNF-α, IL-1ß, and IL-6), as well as a decrease in histopathological changes and TNF-α immunoexpression in paw tissues. Moreover, Mlx-Cur-NP demonstrated noteworthy potentiation in pharmacological effects compared to free compounds and mono-compound-loaded nanoparticles. Thus, the association of meloxicam with curcumin in a biodegradable nanocarrier system could provide a promising anti-pyretic, anti-nociceptive, and anti-inflammatory therapeutic approach for acute conditions.

Pros and Cons of Dietary Vitamin A and Its Precursors in Poultry Health and Production: A Comprehensive Review.

Vitamin A is a fat-soluble vitamin that cannot be synthesized in the body and must be obtained through diet. Despite being one of the earliest vitamins identified, a complete range of biological actions is still unknown. Carotenoids are a category of roughly 600 chemicals that are structurally related to vitamin A. Vitamin A can be present in the body in the form of retinol, retinal, and retinoic acid. Vitamins are required in minute amounts, yet they are critical for health, maintenance, and performing key biological functions in the body, such as growth, embryo development, epithelial cell differentiation, and immune function. Vitamin A deficiency induces a variety of problems, including lack of appetite, decreased development and immunity, and susceptibility to many diseases. Dietary preformed vitamin A, provitamin A, and several classes of carotenoids can be used to meet vitamin A requirements. The aim of this review is to compile the available scientific literature regarding the sources and important functions, such as growth, immunity, antioxidant, and other biological activities of vitamin A in poultry.

Physiological dynamics in broiler chickens under heat stress and possible mitigation strategies.

High ambient temperature has emerged as a major constraint for the future development of the poultry industry, especially in the tropics and subtropics. The scarcity of resources coupled with harsh environmental conditions is the most crucial predicaments in the way to rationalize optimum production of broiler. Heat stress disturbs the physiological biochemistry of the broiler which ultimately reduces feed intake and feed efficiency which ultimately results in reduced performance and productivity. Under hot environmental conditions, feed utilization is disturbed by the deposition of fat and oxidative stress. In addition, changes in blood cells, acid-base balance, immune response, liver health, and antioxidant status are some of the major dynamics altered by heat stress. The broilers have a narrow range of temperatures to withstand heat stress. In this review, we have discussed the various physicochemical changes during heat stress, their possible mechanisms, and mitigation strategies to reduce heat stress.

Dietary vitamin D: growth, physiological and health consequences in broiler production.

Vitamins are needed in trace amounts in dietary formulations for poultry; however, they are critical for the health, maintenance, and performance of important body organs. Broilers have a lot of leg issues because of their rapid development and lack of exercise. Because of commercial broilers have limited access to direct sunlight, vitamin D supplementation in the feed is critical to reducing the risk of bone deformation and maximizing development. Vitamin D deficiency causes skeletal abnormalities, which may lead also to financial problems. The latest scientific findings on the source, metabolism, mechanisms of action, and functions of vitamin D in broilers are the subject of this review paper.

Dietary tea tree (Melaleuca alternifolia) essential oil as alternative to antibiotics alleviates experimentally induced Eimeria tenella challenge in Japanese quails.

Coccidiosis is one of the most common infectious diseases seen in Japanese quails. The current study was conducted to evaluate the impact of tea tree essential oil (TTEO) on growth performance and intestinal health of quails in response to Eimeria tenella challenge. A total of 250 Japanese quails were divided into five treatments: untreated uninfected (negative control); untreated infected (positive control); infected + Amprolium; infected and 1% TTEO; infected and 2% TTEO. Except negative control, all groups were orally dosed with 5 × 104 sporulated oocysts of E. tenella. The results revealed that supplementation of 1% TTEO and treatment of amprolium improved feed intake, weight gain and feed conversion ratio in infected quails compared to the positive control. Similarly, lesion score and mortality was significantly (p < 0.01) reduced in quails supplemented with 2% TTEO and amprolium treated birds. Moreover, oocysts counts and histological features of caecum in infected birds were reversed in 1% TTEO and amprolium treatment. The histological findings of amprolium and 1% TTEO supplemented quails showed intact intestinal villi with mild sloughed epithelium. In conclusion, 1% TTEO can be safely used to control coccidiosis in Japanese quails as natural effective compound.

Biomonitoring of heavy metals and their association with DNA damage in Indian peafowl (Pavo cristatus) under captivity.

Environmental pollution and changing climatic conditions are likely to damage biodiversity not only on organismal level but on molecular level as well. The aim of the present study was to find the concentration of heavy metals in soil, water, feed, feathers, and blood and association of heavy metals with DNA damage of P. cristatus. The results showed that lead (Pb) was significantly (P < 0.01) higher in soil and cadmium (Cd) was significantly (P < 0.01) higher in soil and water. Chromium (Cr), zinc (Zn), nickel (Ni), and cobalt (Co) were significant (P < 0.01) in feed. Manganese (Mn) was significantly (P < 0.01) higher in feed and soil (surface). In addition, Pb and Cd concentrations were significant (P < 0.01) in feathers while Cr and Zn concentrations were significantly (P < 0.01) higher in feces. Nickel was significantly (P < 0.01) higher in feathers and eggshell while Mn and Co concentrations were significantly (P < 0.01) higher in blood and feces, respectively. Furthermore, significant positive correlation between Pb (rs = 0.75; P < 0.05) and Cd (rs = 0.67; P < 0.05) concentrations in blood with tail DNA was found. It was concluded that heavy metals exist in the soil, water, feathers, and blood and have association with DNA damage of P. cristatus.

Oestrogen And Progesterone Receptors' Expression Pattern In Fibro-Adenoma Of The Female Breast.

BACKGROUND: Fibro-adenoma is the most common benign condition of the female breast comprising about 68% of all breast lumps. Fibroadenoma is an independent risk factor for the development of breast cancer. Complex fibroadenoma has a 2-3-fold increased risk ratio and simple fibroadenoma has 1.49 times increased risk ratio of developing cancer than the normal population over a period of 20 years. This study aimed to qualitatively check the frequency of oestrogen receptor-positive and progesterone receptor-positive cases of fibroadenoma in our region. METHODS: This cross-sectional study was conducted in the pathology department of Ayub Medical College, Abbottabad from June 2020 to December 2021. Biopsy confirmed cases of fibroadenoma were examined using immune-histochemical stains to score qualitatively the expression pattern of ER and PR. Data was analyzed and assessed using SPSS version 25. A p-value of ≤0.05 was considered statistically significant. RESULTS: The mean age of patients who presented with fibro-adenoma was 24.5±9.29 years with a median age of 21.5 years. In most cases, oestrogen receptor expression was mild 23 (54.76%) whereas progesterone receptor expression was severe 19 (45.23%). On chi-square test, the pattern of progesterone receptor expression for the category of hormone intake showed significant differences. Whereas, the pattern of oestrogen receptor expression for the categories of marital status, history of hormone intake, history of menstrual cycle and type of fibroadenoma showed no statistically significant difference. CONCLUSIONS: Further study into the pathogenesis of fibroadenoma is required to understand the role of ER and PR and explore the therapeutic potential of such drugs that affects these receptors.

Integrating In Silico and In Vitro Approaches to Screen the Antidiabetic Properties from Tabernaemontana divaricata (Jasmine) Flowers.

The purpose of this study was to assess different in vitro biological activities such as phytochemical constituents, enzymatic antioxidant status, cytotoxicity through hemolytic activity, and antidiabetic potential of plant methanolic extract through glucose uptake by yeast cells. Further, using in silico approach by the SwissADME technique the drug-likeness rules for bioactive components were characterized, while potential interactions were identified via molecular docking of a ligand with target proteins by GOLD 5.3.0. The results showed that T. divaricata was rich in TPC and TFC, i.e., 62.32 ± 4.02 and 24.53 ± 0.61, respectively, and the cytotoxic potential was 10% towards human RBCs, while protein estimation revealed the presence of protein in the extract, which was 22.82 ± 4.6. DPPH assay in comparison with ascorbic acid and several enzymatic assays, such as CAT, SOD, and POD, showed maximum antioxidant potential, i.e.,15.9 ± 2.33%, 65.57 ± 13.4%, 3.02 ± 3.4, 15.87 ± 0.5, and 0.74 ± 0.2, respectively. Glucose uptake by yeast cells, i.e., α-amylase and α-glucosidase, showed a maximum antidiabetic potential such as 75.11 ± 1.44%, 41.81 ± 3.75%, and 35.9 ± 1.24%, respectively. Our results indicate that the methanolic extract of T. divaricata has antioxidant potential and inhibits α-amylase and α-glucosidase activity and possesses maximum antidiabetic potential. The results provide scientific proof that the medicinal plant being studied is a powerful source of natural antioxidant, antidiabetic, and medicinally significant substances. In silico study, using a molecular docking, unveiled that two compounds showed good interactions with 5kzw protein with considerable binding affinities and fulfilled docking parameters. It may conclude that T. divaricata is an important vegetable with a potent source of natural antioxidants and antidiabetic activity justifying its traditional use in green therapeutics.

Perspective, Opportunities and Challenges in Using Fennel (Foeniculum vulgare) in Poultry Health and Production as an Eco-Friendly Alternative to Antibiotics: A Review.

Following the European Union's restriction on antibiotic growth promoters, research on enhancing gut health has been accelerated. As the poultry industry is facing issues that were previously managed by antimicrobial growth promoters, the hunt for the best remedies continues to find suitable alternatives. Simultaneously, social pressure is mounting to reduce the usage of antibiotics and replace them with other feed additives. Consumers believe a number of accessible options to be safe, with phytogenics playing a crucial role. This review describes how the use of fennel seeds could be beneficial for poultry. An overview of the broad chemical diversity of fennel is presented together with their physicochemical and biological properties. According to investigations, fennel seeds have a variety of biological effects in birds, including improved performance, higher immune cell proliferation, reduced oxidative stress, and boosted antibody titers against infectious diseases. The efficacy of poultry outcomes is determined by the stage and age of the plants, the extraction process, the geographical location, the chicken species, management techniques, and the concentrations administered. The present review focuses on the effects of fennel seeds as a feed additive on poultry growth, carcass quality, blood biochemistry, antioxidant activity, immunity, and microbiological aspects.
