YouTube faced a major lawsuit by Viacom International in 2011 that nearly resulted in the discontinuation of the website. The lawsuit was filed due to alleged copyright infringement of Viacom's material by YouTube.

بعد إطلاق يوتيوب أصبح من السهل نشر الأفلام ليشاهدها المستخدمون حول العالم، وأصبح العديد من الهواة مثل الكوميديين والسياسيين والموسيقيين ينشرون مقاطع مصورة باستمرار، مثل بات كونديل.
On November 11, 2021, after testing out this change in March of the same year, YouTube announced it would start hiding dislike counts on videos, making them invisible to viewers. The company stated the decision was in response to experiments which confirmed that smaller YouTube creators were more likely to be targeted in dislike brigading and harassment.

Vitamin C plays important roles kakım a cofactor in many enzymatic reactions and bey an antioxidant against oxidative stress. Bey some mammals including humans cannot synthesize vitamin C bile novo from glucose, its uptake from dietary sources is essential, and is mediated by the sodium-dependent vitamin C transporter 1 (SVCT1). Despite its physiological significance in maintaining vitamin C homeostasis, the structural basis of the substrate transport mechanism remained unclear.
Superimposition of the protomers of the inward-open and substrate-free occluded structures relative to the core domain revealed that the entire gate domain tilts toward the cytoplasmic side of the core domain in the same protomer, with TMs 6 and 13 outwardly rotated in the transition from the inward-open state to the substrate-free occluded state (Fig. 4f). This tilting motion of the gate domain is likely related to the rocking bundle-like mechanism proposed in previous studies of UraA monomer and dimer su alti tasima araci structures19,20. We observed the flipping of the aromatic sidechains of Phe112 in the core domain and Phe436 in the gate domain through the conformational change (Fig.

To examine the functional importance of the residues comprising the substrate binding pocket, we measured the transport activities of hSVCT1 mutants by a cellular ascorbic acid uptake assay, based on its reducing ability (Fig. 3e). The results demonstrated that the alanine mutations of the residues involved in the coordination of two sodium ions significantly decreased the transport activity, confirming the sodium-dependent binding manner of the substrate suggested from the structure.

The mutation of Thr59, which interacts with the tail of the vitamin C molecule, caused a partial impairment of substrate uptake, consistent with the proposed weak recognition of this region. Although we did hamiş detect any direct interactions between the substrate and residues such birli Ser382 and Pro384, mutants of these residues exhibited rather decreased transport activities. These residues may have a role in substrate affinity by forming and stabilizing the hydrophilic pocket.
In cases where the entire kent is banned due to one particular video, YouTube will often agree to remove or limit access to that videoteyp in order to restore service.[239]
