Tetraacylgermanes are known as highly efficient photoinitiators. Herein, the synthesis of mixed tetraacylgermanes 4 a-c and 6 a-e with a nonsymmetric substitution pattern is presented. Germenolates are crucial intermediates of these new synthetic protocols. The synthesized compounds show increased solubility compared with symmetrically substituted tetraacylgermanes 1 a-d. Moreover, these mixed derivatives reveal broadened n-π* absorption bands, which enhance their photoactivity. Higher absorption of these new compounds at wavelengths above 450 nm causes efficient photobleaching when using an LED emitting at 470 nm. The quantum yields are in the range of 0.15-0.57, depending on the nature of the aroyl substituents. On the basis of these properties, mixed-functionalized tetraacylgermanes serve as ideal photoinitiators in various applications, especially in those requiring high penetration depth. The synthesized compounds were characterized by elemental analysis, IR spectroscopy, NMR and CIDNP spectroscopy, UV/Vis spectroscopy, photolysis experiments, and X-ray crystallography. The CIDNP data suggest that the germyl radicals generated from the new tetraacylgermanes preferentially add to the tail of the monomer butyl acrylate. In the case of 6 a-e only the mesitoyl groups are cleaved off, whereas for 4 a-c both the mesitoyl and the aroyl group are subject to α-cleavage.The best-known cutaneous manifestations of septicemia in the skin are the so-called "septic vasculitis" and "septic vasculopathy," which represent two sides of the same pathogenetic process. The spectrum of cutaneous presentations of septicemia is, however, more complex, extending beyond septic vasculitis/vasculopathy. We describe the exceptional histopathological findings of skin lesions associated with Stenotrophomonas maltophilia septicemia, featuring a lymphohistiocytic infiltrate characterized by predominance of foamy macrophages containing granular basophilic material negative for PAS, Gram, Fite, and Grocott. Albeit an uncommon occurrence, S. maltophilia septicemia should be included in the broad differential diagnosis of cutaneous lesions occurring in immunocompromised individuals with worsening general conditions. Awareness of these histopathological findings may facilitate the identification of this insidious infectious agent as a source of nosocomial septicemia.
To describe the surgical reduction of luxation of the triceps brachii tendon in a dog.

One 2.5-year-old 2.58 kg castrated male toy poodle.

Clinical case report.

The dog displayed intermittent, non-weight bearing lameness of the right forelimb for approximately 18 months before presenting at the veterinary medical center. Medial subluxation of the right elbow joint was detected by palpation. The Campbell test was consistent with an increased range of motion during supination. At ultrasonographic examination, medial luxation of the triceps brachii tendon was noted, whereas collateral ligaments appeared normal. No skeletal deformities were found on radiographs of the right forelimb. The luxation of the triceps brachii tendon was surgically corrected with antirotational suture, a stopper pin, medial retinaculum release, and imbrication of the lateral retinaculum.

The right triceps brachii tendon and elbow joint were successfully reduced. selleck compound Gait returned to normal by 55 days postoperatively. No implant failure or recurrence were observed 3.5 years after surgery.

Surgical reduction of a luxation of the triceps brachii tendon in a dog resolved lameness and restored the range of motion of the affected elbow, leading to good long-term outcome.

In primary care, there is a need for simple and cost-effective tool that will allow the determination of the risk of coronary artery disease (CAD). We aimed to research the value of glycosylated hemoglobin (HbA1c) in the prediction of coronary artery disease.

Patients admitted to the outpatient clinic of the Cardiology for angiography were retrospectively screened. Patients with diabetes or with HbA1c of 6.5 or above were excluded. Comparative HbA1c data were obtained according to the stenosis groups. Logistic regression analysis was used to investigate the risk factors affecting stenosis positivity.

Of the study group, 120 patients were without any stenosis in any coronary artery, 56 patients were with >50% stenosis in one coronary artery, and 71 patients were with >50% stenosis in more than one coronary artery. There was a statistically significant difference between HbA1c measurements according to the degree of stenosis (P=.001 and P<.01, respectively). The odd ratio for HbA1c was 6.260 (95% CI 3,160-12,401). According to the stenosis positivity, the cutoff point for HbA1c was found to be 5.6 and above. In the regression analysis, HbA1c was an independent risk factor for CAD. One unit increase in HbA1c level increases the risk of stenosis up to 12.4-fold (95% CI 5,990-25,767).

The study showed HbA1c can be used as an independent marker in determining the probability and severity of coronary artery disease in non-diabetic individuals and as a useful marker in primary care predicting CAD.

PERP (p53 apoptosis effector related to PMP22) localizes to desmosomes and suppresses squamous cell carcinoma development. Loss of PERP leads to worse local control in head and neck squamous cell carcinoma (HNSCC), likely by destabilizing desmosomes. We evaluated PERP loss at HNSCC surgical margins as a predictor of local relapse.

Combining discovery (n = 17) and validation (n = 31) cohorts, we examined membranous PERP protein expression by immunohistochemistry in surgical mucosal margins with competing risk analysis of the relationship between local relapse and PERP expression.

Of the 44 analyzable patients, the 2-year cumulative incidence of local relapse was 44.4% for the PERP-negative group and 16.4% for the PERP-positive group (P = .01). A trend toward worse progression-free survival (P = .09) and overall survival (P = .06) was observed with loss of PERP.

PERP loss at surgical margins is associated with higher risk of local recurrence in HNSCC, warranting further evaluation in a larger prospective study.
