A preliminary assessment of the efficacy of anticancer measures in malignant stomach neoplasms

Three cases of erosive pustular dermatosis of the scalp are reported. In all patients the dermatosis was characterized by pustular, erosive, and crusted lesions; in addition, two patients had areas of scarring alopecia. The results of laboratory tests, bacteriologic and mycologic investigations, and histopathologic examination were nondiagnostic. Although erosive pustular dermatosis of the scalp is characterized by a nonpathognomonic clinical and histopathologic picture, it probably represents a disease entity.

A GRASP approach for the extended car sequencing problem

This paper presents a solution procedure for a new variant of the Car Sequencing Problem (CSP) based on the GRASP metaheuristic. In this variant, called xCSP (extended CSP), the aim is to satisfy the hard constraints of the CSP while scheduling the maximum possible number of cars with specific options at specific times of the day in order to satisfy other production requirements. Additional constraint ratios are likewise considered that force at least a minimum specific number of consecutive options. An extension of the CSP is formalized in this paper and computational results are presented using available on-line instances that verify the good performance of a GRASP procedure defined for the xCSP.     

Understanding the High Voltage Behavior of LiNiO2 Through the Electrochemical Properties of the Surface Layer

Nickel-rich layered oxides are adopted as electrode materials for EV's. They suffer from a capacity loss when the cells are charged above 4.15 V versus Li/Li⁺. Doping and coating can lead to significant improvement in cycling. However, the mechanisms involved at high voltage are not clear. This work is focused on LiNiO₂ to overcome the effect of M cations. Galvanostatic intermittent titration technique (GITT) and in situ X-ray diffraction (XRD) experiments are performed at very low rates in various voltage ranges (3.8–4.3 V,). On the “4.2–4.3 V” plateau the R2 phase is transformed simultaneously in R3, R3 with H4 stacking faults and H4. As the charge proceeds above 4.17 V cell polarization increases, hindering Li deintercalation. In discharge, such polarization decreases immediately. Upon cycling, the polarization increases at each charge above 4.17 V. In discharge, the capacity and dQ/dV features below 4.1 V remain constant and unaffected, suggesting that the bulk of the material do not undergo significant structural defect. This study shows that the change in polarization results from the electrochemical behavior of the grain surface having very low conductivity above 4.17 V and high conductivity below this threshold. This new approach can explain the behavior observed with dopants like tungsten.     

The prevention of infectious-inflammatory complications in the postoperative period in percutaneous surgical interventions in patients with urolithiasis

The paper describes a number of modifications in the operative procedures, pre-, intra- and postoperative antibacterial treatment introduced to decrease the number and severity of infectious-inflammatory complications of endourological surgery for urolithiasis; presents the results of anti-bacterial prophylaxis of urinary infection aggravation in 29 patients suffering from urolithiasis combined with renal anomalies. Antibacterial treatment was performed with ftorquinolone drug ciprinol (ciprofloxacin hydrochloride) made in Slovenia. 18 patients received ciprinol twice a day at a dose 500 mg 3-5 days before the operation and within 5-7 postoperative days. The other 11 patients received the drug intravenously (100 mg in drops) in parallel with initial anesthesia and during 1-2 postoperative days. It was continued orally within the next 5-6 postoperative days. The analysis of ciprinol pharmacokinetic profile showed its concentrations in the blood and urine to surpass minimal inhibitory concentration for the majority of the isolated microorganisms. Out of 18 patients treated with oral ciprinol, postoperative aggravation of pyelonephritis occurred in 3 (16.7%) versus 8 (40%) cases out of 20 controls. 11 patients on intravenous ciprinol developed no complications. The conclusion is made on high efficacy of preoperative antibacterial preparation and of intraoperative antibacterial therapy continued for some time after the surgery in cases of percutaneous endoscopic surgical interventions for urolithiasis attended by chronic urinary infection. The antibacterial treatment brings about a 2-3-fold decrease in the occurrence of postoperative inflammatory complications.     

Reduced adipose tissue lipoprotein lipase responses, postprandial lipemia, and low high-density lipoprotein-2 subspecies levels in older athletes with silent myocardial ischemia

BACKGROUND: Radioimmunoguided surgery (RIGS) by means of radiolabeled monoclonal antibodies and a probe has been reported to be useful in recognizing subclinical tumor deposits during operation. Aim of this study was to understand the limits of this technique and to assess the potential diagnostic use of RIGS in colorectal cancer surgery. METHODS: Monoclonal antibody B72.3 reacting with TAG 72 antigen, labeled with iodine 125, was injected in 32 patients with primary tumors and in 22 patients with recurrent colorectal cancer. One hundred thirty-three suspected tumor sites were evaluated during operation by means of probe and resected with immunohistochemistry as control. RESULTS: Primary tumor sites were localized by RIGS in 60% of cases, and recurrent sites were localized in 82% of cases. There was a significant correlation both for primary (p < 0.001) and recurrent (p < 0.001) tumor sites between intraoperative RIGS findings and TAG 72 tumor antigen expression. Results obtained with the probe were instrumental in modifying the surgical approach in six (27%) of 22 patients with recurrences, allowing the removal of tumor masses that would otherwise have been overlooked. CONCLUSIONS: The results of RIGS seems to be encouraging in terms of clinical use. The potential high diagnostic resolution appears to improve surgical ablation of colorectal cancer, especially in patients with recurrent cancer or suspected recurrent tumors who have negative results for intraabdominal disease by all other roentgenographic criteria with rising carcinoembryonic antigen or TAG 72 antigen levels.     

A new synbiotic dairy food containing lactobionic acid and Lactobacillus casei

As well as its beneficial health properties, the incorporation of the prebiotic lactobionic acid (LBA) in fermented dairy products can provide a technological advantage due to its gelling capacities. This study aimed to develop a new functional dairy product containing LBA synthesised within the process itself by the bacterium Pseudomonas taetrolens. A probiotic Lactobacillus casei strain was introduced through a sequential fermentation system. After incubation, in the case of the most effective experimental procedure, a synbiotic fermented milk with 30 g/L of prebiotic LBA was obtained, together with an active L. casei population of 10⁹ cfu/mL and <1% lactose content.     

Scope and limitations of cranial computerized tomography (author's transl)

Cranial computerized tomography (CT) has revolutionized the scope of diagnostic procedures in intracranial diseases. The method is based on the quantitative registration of x-ray absorption and enables many different pathological features within the skull to be directly visualized for the first time on the tomogram. Cerebral haemorrhage and encephalomalacia can be immediatley differentiated on the basis of the totally different appearance on CT. In the case of tumours, the additional administration of the contrast medium intravenously provides enhancement of the diagnostic evidence. Atrophic processes can be diagnosed by means of CT without recourse to additional neuroradiological methods and this facilitation is of particular value in neuropaediatrics. Orbital processes can be easily spotted due to the high definiation matrix of image. The limitations of CT are based on physical conditions.
