BACKGROUND: Cow's milk protein allergy (CMPA) affects between 0.6 and 0.9% of the general population, and its treatment implies the total elimination of the intake of this protein. Camel's milk has been suggested as an alternative for patients over one year of age who suffer from CMPA due to the difference in the amino acid sequence from that of cow's milk. The objective of this study was to evaluate the safety and tolerability of camel's milk in children with CMPA. METHODS: Crossed clinical trial for the use of camel's milk vs...

Parkinson's disease is the most common neurodegenerative disorder after Alzheimer's disease, with the majority of cases being sporadic or "idiopathic". The aetiology of the sporadic form is still unknown, but there is a broad consensus that Parkinson's disease involves multiple pathways. In previous human post-mortem studies investigating substantia nigra of parkinsonian subjects, gene expression alterations in various metabolic pathways including protein folding, trafficking, aggregation, ubiquitination and oxidative stress were found...

Camelina sativa is a re-emerging low-input oilseed crop that has great potentials. It is necessary to ameliorate camelina oils for optimized fatty acid composition that can meet different application requirements. Camelina seed contains significant amounts of C20-C24 very long-chain fatty acids (VLCFAs) that may not be desirable. We demonstrated that these VLCFAs can be effectively reduced by deactivating the Fatty Acid Elongase1 (FAE1) in camelina. The allohexaploid camelina contains three alleles of FAE1 genes...

Monoclonal antibodies have revolutionized cancer therapy. However, delivery to tumor cells in vivo is hampered by the large size (150 kDa) of conventional antibodies. The minimal target recognition module of a conventional antibody is composed of two non-covalently associated variable domains (VH and VL). The proper orientation of these domains is mediated by their hydrophobic interface and is stabilized by their linkage to disulfide-linked constant domains (CH1 and CL). VH and VL domains can be fused via a genetic linker into a single-chain variable fragment (scFv)...

Cold environment is the main constraint for tea plants (Camellia sinensis) distribution and tea farming. We identified two tea cultivars, called var. sinensis cv. Shuchazao (SCZ) with a high cold-tolerance and var. assamica cv. Yinghong9 (YH9) with low cold-tolerance. To better understand the response mechanism of tea plants under cold stress for improving breeding, we compared physiological and biochemical responses, and associated genes expression in response to 7-day and 14-day cold acclimation, followed by 7-day de-acclimation in these two tea cultivars...

The human coronaviruses (CoV) include HCoV-229E, HCoV-OC43, HCoV-NL63, and HCoV-HKU1, some of which have been known for decades. The severe acute respiratory syndrome (SARS) CoV briefly emerged into the human population but was controlled. In 2012, another novel severely human pathogenic CoV-the Middle East Respiratory Syndrome (MERS)-CoV-was identified in the Kingdom of Saudi Arabia; 80% of over 2000 human cases have been recorded over five years. Targeted research remains key to developing control strategies for MERS-CoV, a cause of mild illness in its camel reservoir...

Cytotoxic T‑lymphocyte antigen‑4 (CTLA‑4) is a critical negative regulator of immune responses. CTLA‑4 is rapidly upregulated following T‑cell activation, and then binds to B7 molecules with a higher affinity than CD28. CTLA‑4 may abolish the initiation of the responses of T cells by raising the threshold of signals required for full activation of T cells, and it also may terminate ongoing T-cell responses. This regulatory role has led to the development of monoclonal antibodies (mAbs) designed to block CTLA‑4 activity for enhancing immune responses against cancer...

The gut microbiomes of birds and other animals are increasingly being studied in ecological and evolutionary contexts. Numerous studies on birds and reptiles have made inferences about gut microbiota using cloacal sampling, however, it is not known whether the bacterial community of the cloaca provides an accurate representation of the avian gut microbiome. We examined the accuracy with which cloacal swabs and faecal samples measure the microbiota in three different parts of the gastrointestinal tract (ileum, caecum, and colon) using a case study on juvenile ostriches, Struthio camelus, and high-throughput 16S rRNA sequencing...

The available information about anatomical characteristics of the cardiovascular system of the alpaca (Vicugna pacos, Linnaeus 1758) is scarce. The general objective of this work was to describe its heart anatomy. We dissected six adult animals and five neonates. The heart of the alpaca was located in the middle mediastinum, with a craniocaudal extension from the third to the sixth rib. No ligament that connected the fibrous pericardium to the sternum or to the diaphragm was detected. In the right atrium, there was a developed crista terminalis and small pectinate muscles...

Angiogenesis, the formation of new blood vessels from pre-existing vasculature, plays a decisive role for the rapid growth of avian follicles. Compared to mammals, few data on the angiogenesis in the avian ovary are available. However, whereas several pro-angiogenic factors in the avian ovary have been recently studied in detail, little information is available on the localization of anti-angiogenic factors. The aim of this study was to determine the localization and possible function of the anti-angiogenic factor thrombospondin-1 (TSP-1) and its receptor CD36 in the ovary of the ostrich using immunohistochemistry and to correlate the results with ultrastructural data...

Polyphenols are secondary metabolites of plants, which are responsible for prevention of many diseases. Polyvinylpolypyrrolidone (PVPP) has a high affinity towards polyphenols. This method involves the use of PVPP column to remove polyphenols under centrifugal force. Standards of gallic acid, epigallocatechin gallate, vanillin, and tea extracts (Camellia sinensis) were used in this study. PVPP powder was packed in a syringe with different quantities. The test samples were layered over the PVPP column and subjected to centrifugation...

Background: Camel milk has been reportedly used to treat dropsy, jaundice, tuberculosis, and diabetes while camel urine is used to treat diarrhea and cancer. However, there is no scientific evidence on the antiulcer activity of camel milk and urine. Thus, the present is designed to investigate the gastroprotective and ulcer healing effect of camel milk and urine on experimentally induced gastric ulcer models in rats. Materials and Methods: The gastroprotective effect was investigated in HCl/EtOH, water-restraint stress (WRS) and non-steroidal anti-inflammatory drugs (indomethacin)-induced ulcer models while ulcer healing activity was investigated in indomethacin-induced ulcer model...

To clarify the source of radiocesium detected in newly emerged tea leaves contaminated just before the time of bud opening by fallout of radionuclides from Fukushima Dai-ichi Nuclear Power Plant, 137CsCl solution (0.185 M Bq mL-1) was applied to the front or the backside surfaces of mature leaves of tea plant (Camellia sinensis L. cv. Yabukita) at the time of bud opening. A 21 days after foliar application, the buds had grown and developed to the three- or four-leaf stage. In the front treatment, almost all (95%) of the applied 137Cs was present in the mature leaves (hot mother leaves)...

In Asia, tea seed oils (seed oils from Camellia oleifera, C. chekiangoleosa, and C. sinensis) are used in edible, medicinal, and cosmetic applications. However, these oils differ in their fatty acid contents, and there is little known about their phenolic compounds. Here we analyzed the phenolic compounds of seed oils from three species gathered from 15 regions of China. Twenty-four phenolic compounds were characterized by HPLC-Q-TOF-MS, including benzoic acids (6), cinnamic acids (6), a hydroxyphenylacetic acid, flavanols (4), flavonols (3), flavones (2), and dihydroflavonoids (2)...

The worldwide spread of smartphones has radically changed the habits of human life, allowing a 24/7 connection with other people. These changes have involved also Medicine with smartphones being able to simplify the clinical practice of physicians. The development of new external devices that can be connected to smartphones has further increased their use with mobile phones converted in portable electrocardiogram or echocardiogram machines. This extraordinary technological improvement seems to be partly in conflict with the classical tools available for the cardiologist, such as the "old" stethoscope that in 2016 had its 200th anniversary...

Horses are critically important for Mongolian herders' livelihoods, providing transportation and food products, and playing important cultural roles. Equine influenza virus (EIV) epizootics have been frequent among Mongolia's horses, with five occurring since 1970. We sought to estimate the prevalence for EIV infection among horses and Bactrian camels with influenza-like illness between national epizootics. In 2016-2017, active surveillance for EIV was periodically performed in four aimags (provinces). Nasal swabs were collected from 680 horses and 131 camels...

Tuckerella japonica Ehara (Acari: Tuckerellidae) feeds on predigested plant cells beneath exposed periderm tissue of 1- to 3+-year-old stems of Camellia sinensis (L.) O. Kuntze (Theaceae) where longitudinal bark splitting occurs. Control samples from these tissues were compared with areas fed upon by T. japonica adults and immatures to characterize types of cellular injury. Stylet diameters ranged from 1.6 to 2.3 µm and were consistent with observed stylet punctures in the stems. Mite saliva was injected along tracts within the cortical tissue and resulted in cell wall disruption, collapsed cells and, in older tissue, hyperplasia...
