RESUMEN
Rumen-protected choline (RPC) promotes benefits in milk production, immunity, and health in dairy cows by optimizing lipid metabolism during transition period management and early lactation. However, the RPC success in dairy cows depends on choline bioavailability, which is affected by the type of protection used in rumen-protected choline. Therefore, our objectives were to determine the effects of a novel RPC on dry matter intake (DMI), identify markers of metabolism and immunity, and evaluate lactation performance. Dry Holstein (n = 48) cows at 245 ± 3 d of gestation were blocked by parity and assigned to control or RPC treatment within each block. Cows enrolled in the RPC treatment received 15 g/d of CholiGEM (Kemin Industries, Cavriago RE, Italy) from 21 d prepartum and 30 g/d of CholiGEM from calving to 21 d postpartum. During the transition period, DMI was measured daily, and blood was sampled weekly for energy-related metabolites such as ß-hydroxybutyrate (BHB), glucose, and nonesterified fatty acids (NEFA), as well as immune function markers such as haptoglobin (Hp) and lipopolysaccharide-binding protein (LPB). Vaginal discharge samples were collected at the calving and 7 d postpartum and stored in microcentrifuge tubes at -80°C until 16S rRNA sequencing. The main responses of body condition score, body weight, DMI, milk yield, milk components, and immune function markers were analyzed using the GLIMMIX procedure of SAS with the effects of treatment, time, parity, and relevant covariates added to the models. The relative abundance of microbiome α-diversity was evaluated by 3 indexes (Chao1, Shannon, and Simpson) and ß-diversity by principal coordinate analysis and permutational multivariate ANOVA. We found no differences in DMI in the pre- and postpartum periods. Cows fed RPC increased the yields of energy- and 3.5% fat-corrected milk and fat yield in primiparous and multiparous cows, with an interaction between treatment and parity for these lactation variables. However, we found no differences in milk protein and lactose up to 150 DIM between treatments. Glucose, NEFA, and BHB had no differences between the treatments. However, RPC decreased BHB numerically (control = 1.07 ± 0.13 vs. RPC = 0.63 ± 0.13) in multiparous on the third week postpartum and tended to reduce the incidence of subclinical ketosis (12.7% vs. 4.2%). No effects for Hp and LPB were found in cows fed RPC. Chao1, Shannon, and Simpson indexes were lower at calving in the RPC treatment than in the Control. However, no differences were found 7 d later for Chao1, Shannon, and Simpson indexes. The vaginal discharge microbiome was altered in cows fed RPC at 7 d postpartum. Fusobacterium, a common pathogen associated with metritis, was reduced in cows fed RPC. Rumen-protected choline enhanced lactation performance and health and altered the vaginal discharge microbiome which is a potential proxy for uterine healthy in dairy cows. The current study's findings corroborate that RPC is a tool to support adaptation to lactation and shed light on opportunities for further research in reproductive health.

Abstract The contamination of natural resources with heavy metals released from steel mills is the primary cause of soil and water pollution in the Dargai Malakand, located on the northern side of Pakistan. Therefore, the present study was aimed to determine the level of heavy metals in soil and water samples of this area. The wild plant growing (nine native plants: Pteris vittata, Populus nigra, Eucalyptus camaldulensis, Persicaria maculosa, Arundo donax, Xanthium strumarium, Verbascum thapsus, Ricinus communis and Parthenium hysterophorus) there were then tested for their phytoremediation capabilities which is an environmentally friendly, generally utilized, and low-cost approach to eliminate heavy metals from polluted soils and water. Soil, water, and effluent samples were taken from the contaminated sites of seven steel mills in Dargai District Malakand and subjected to heavy metals analysis. Based on bioconcentration factor (BCF) and translocation factor (TF) calculated, The highest BCF for zinc was recorded for Pteris vittata roots (3.93), while the lowest value was observed for Verbascum thapsus leaves (0.306). Pteris vittata root showed the highest BCF for iron (1.618), while Ricinus communis leaves showed the lowest (0.023). The highest BCF value for chromium was highest for Populus nigra roots (0.717), while the lowest value was recorded for Persicaria maculosa leaves (0.031). For the selected metals; Fe, Zn and Cr the highest TF were recorded for Pteris vittata (0.988), Verbascum thapsus (0.944) and Xanthium strumairum (0.968) respectively. Therefore, it is recommended that these plants should be grown near to steel mills to reclaim heavy metals from industrial effluent, polluted soil as well as from polluted water.
A contaminação dos recursos naturais com metais pesados ââliberados pelas siderúrgicas é a principal causa da poluição do solo e da água no Dargai Malakand, localizado no lado norte do Paquistão. Portanto, o presente estudo teve como objetivo determinar o teor de metais pesados ââem amostras de solo e água desta área. O cultivo de plantas silvestres (nove plantas nativas: Pteris vittata, Populus nigra, Eucalyptus camaldulensis, Persicaria maculosa, Arundo donax, Xanthium strumarium, Verbascum thapsus, Ricinus communis e Parthenium hysterophorus) foi testado quanto às suas capacidades de fitorremediação, que é um meio ambiente, geralmente utilizado, e abordagem de baixo custo para eliminar metais pesados ââde solos e águas poluídas. Amostras de solo, água e efluentes foram retiradas dos locais contaminados de sete siderúrgicas no distrito de Dargai, Malakand, e submetidas à análise de metais pesados. Com base no fator de bioconcentração (BCF) e fator de translocação (TF) calculados, o maior BCF para zinco foi registrado para as raízes de Pteris vittata (3,93), enquanto o menor valor foi observado para as folhas de Verbascum thapsus (0,306). A raiz de Pteris vittata apresentou o maior BCF para ferro (1,618), enquanto as folhas de Ricinus communis apresentaram o menor (0,023). O maior valor de BCF para cromo foi maior para raízes de Populus nigra (0,717), enquanto o menor valor foi registrado para folhas de Persicaria maculosa (0,031). Para os metais selecionados, Fe, Zn e Cr, os maiores TF foram registrados para Pteris vittata (0,988), Verbascum thapsus (0,944) e Xanthium strumairum (0,968), respectivamente. Portanto, recomenda-se que essas plantas sejam cultivadas próximas a siderúrgicas para recuperar metais pesados ââde efluentes industriais, solo poluído e água poluída.

Immunohistochemical and DNA results are described in a patient with sarcoglycanopathy. Immunostaining was comparatively normal for alpha-, attenuated for beta- and delta-, and markedly attenuated for gamma-sarcoglycan, thus sarcoglycanopathy was diagnosed, presumably a gamma-sarcoglycanopathy. Unexpectedly, two alpha-SGP-related pathogenic mutations were identified in compound heterozygosity in the SGCA gene: c.229C > T (p.Arg77Cys) in exon 3 and c.850C > T (p.Arg284Cys) in exon 7. These are discussed together with six additional changes detected in SGCB, SGCG and SGCD.
