In this study, an attempt was made to minimize the corrosion rate and maximize pitting potential of dissimilar metal welded joints of A387-Gr91/AISI316 steels. Process parameters of the pulsed current gas tungsten arc welding (PCGTAW) including of peak current (P), background current (B), pulse frequency (F), and on time percentage (O) were chosen as the influencing factors on corrosion behavio...

DESCRIPTION A 71-year-old right-hand-dominant retired man complains of inability to straighten the thumb, middle finger, and small finger of his left hand. This symptom has been progressively worsening over the past 2 or 3 years. On examination, the 3 affected digits cannot be fully extended, either passively or actively. There is a thick band of fibrous tissue tethering each digit in its contr...

In 1987 we noticed excess adipose tissue in a patient with arm lymphedema and later, objective studies confirmed this clinical finding in patients with non-pitting arm lymphedema following breast cancer. A prospective study was begun in 1993, and its long-term results (15 years) shows overall complete reduction of the excess volume in patients with non-pitting arm lymphedema and that adipose ti...

BACKGROUND Novel immune checkpoint inhibitors have been often utilized for different types of malignancies as salvage therapy with varying success. One obstacle to immune checkpoint inhibitor use is the higher incidence of immune-mediated side effects that can prompt discontinuation of therapy. Remitting seronegative symmetrical synovitis with pitting edema has been described with immune checkp...

Correspondence A surgical treatment for anxiety-triggered palmar hyperhidrosis is not unlike treating tearfulness in major depression by severing the nerves to the lacrimal glands SIR, The recent study of Krogstad et al. 1 in this Journal, reporting on the daily pattern of sweating and response to stress in patients with palmar hyperhidrosis, is an important contribution to the clinical literat...

Plum bark necrosis stem pitting-associated virus (PBNSPaV) causes the plum bark necrosis stem pitting-associated disease. We obtained the complete genome of a PBNSPaV isolate (PBNSPaV-TA) using small RNA deep sequencing followed by overlapping RT-PCR. To our knowledge, this is the first report of a completed genome of PBNSPaV identified from cherry trees.

Numbness within the thumb involving palmar aspect with three and a half digits as division is common presentation of peripheral nerve injury. However, it rarely observed to be presented numbness at ulnar-palmar side thumb, where longitudinal melanonychia on nail plate acts division. We present case that reveals concurrence suffered from injury during course occupational therapy.

Normal tendons, normal palmar aponeuroses and specimens from patients with Dupuytren's disease, namely apparently normal palmar aponeuroses and contracture bands were subjected to elastase and chondroitinase ABC digestion. Maximum Young's modulus, normalized hysteresis loop and residual elongation were determined before and after enzyme treatment. In normal tendons, normal and apparently normal...

AIM We report a case of ulnar and palmar arch artery aneurysm in a 77 years old man without history of any occupational or recreational trauma, vasculitis, infections or congenital anatomic abnormalities. We also performed a computed search of literature in PUBMED using the keywords "ulnar artery aneurysm" and "palmar arch aneurysm". CASE REPORT A 77 years old male patient was admitted to hos...

Stainless steels have good corrosion resistance in many environments but welding or aging can decrease their resistance. This work focused on the effect of aging time and ultrasonic nano-crystal surface modification on the passivation behavior of 316L stainless steel. In the case of slightly sensitized 316L stainless steel, increasing the aging time drastically decreased the pitting potential, ...
