we report the case of a three-year-old girl who complained from dysphagia and post-prandial vomiting since she was 6months old. several diagnostic work-ups were performed for her problem. upper gi endoscopy was normal but barium swallow revealed an external pressure effect over upper part of the esophagus (figure 1) and the ct angiography of thoracic aorta showed that this external pressure eff...

let g be a (p, q) graph. let f : v (g) → {1, 2, . . . , k} be a map. for each edge uv, assign the label gcd (f(u), f(v)). f is called k-prime cordial labeling of g if |vf (i) − vf (j)| ≤ 1, i, j ∈ {1, 2, . . . , k} and |ef (0) − ef (1)| ≤ 1 where vf (x) denotes the number of vertices labeled with x, ef (1) and ef (0) respectively denote the number of edges labeled with 1 and not labeled with 1....

objective(s): the janus kinase-signal transducers and activators of transcription signaling pathway (jak/stat pathway) play an important role in proliferation of breast cancer cells. previous data showed that inhibition of stat3 suppresses the growth of breast cancer cells, but the associated mechanisms are not well understood. this study aims to investigate the effect and associated mechanisms...

Let G be a (p, q) graph. Let f : V (G) → {1, 2, . . . , k} be a map. For each edge uv, assign the label gcd (f(u), f(v)). f is called k-prime cordial labeling of G if |vf (i) − vf (j)| ≤ 1, i, j ∈ {1, 2, . . . , k} and |ef (0) − ef (1)| ≤ 1 where vf (x) denotes the number of vertices labeled with x, ef (1) and ef (0) respectively denote the number of edges labeled with 1 and not labeled with 1....

Palmityl coenzyme A was found to inhibit and inactivate both purified yeast and crude rat liver glucose 6-phosphate dehydrogenase. The yeast enzyme was inhibited 50% at a concentration of 0.0031 mm. The inhibition was strictly competitive and reversible with respect to glucose 6-phosphate and of the mixed type with respect to TPN. Bovine serum albumin and hydroxylamine both prevented and revers...

Succinyl coenzyme A:acetoacetate coenzyme transferase (EC 2.8.3.5), an initiator of ketone body usage and absent in normal liver, has been shown to be located in mitochondria from Morris hepatoma 7288ctc using differential and density gradient centrifugation. Furthermore, tumor mitochondrial subfractionation revealed that this transferase is associated with the matrix-soluble proteins. Comparis...
