Enhancing practicality and efficiency of deepfake detection.

The proliferation of deepfake generation has become increasingly widespread. Current solutions for automatically detecting and classifying generated content require substantial computational resources, making them impractical for use by the average non-expert individual, particularly from edge computing applications. In this paper, we propose a series of techniques to accelerate the inference speed of deepfake detection on video data.

Are Redox-Active Centers Bridged by Saturated Flexible Linkers Systematically Electrochemically Independent?

The extent to which electrophores covalently bridged by a saturated linker are electrochemically independent was investigated considering the charge/spin duality of the electron and functionality of the electrophore as a spin carrier upon reduction. By combining computational modeling with electrochemical experiments, we investigated the mechanism by which tethered electrophores react together within 4,4'-oligo[n]methylene-bipyridinium assemblies (with n=2 to 5). We show that native dicationic electrophores (redox state Z=+2) are folded prior to electron injection into the system, allowing the emergence of supra-molecular orbitals (supra-MOs) likely to support the process of the reductive σ bond formation giving cyclomers.

Sex-specificity in Surgical Stages of Lung Cancer in Young Adults.

Background: Young Patients with lung cancer represent a distinct subset of patients with this neoplasm. Young International studies show increased lung cancer rates in females, while the incidence in males continues to decline. There is evidence to suggest that this trend recurs in younger patients.

High efficiency photocatalytic degradation of Ambroxol over Mn doped TiO: Experimental designs, identification of transformation products, mineralization and mechanism.

Ambroxol (AMB) is a drug commonly used for chronic bronchitis prevention. Once released in surface water, this recalcitrant chemical becomes a hazardous pollutant. Here, we investigated the ability of 1% Mn-doped TiO (Mn-TiO) to mineralize AMB by photocatalysis.

Occurrence and seasonal variation of aflatoxin M in raw cow milk collected from different regions of Algeria.

Background And Aim: Aflatoxins are metabolites of molds that exert potentially toxic effect on animals and humans. This study aimed to investigate the occurrence of aflatoxin M (AFM) in raw cow milk collected during 1 year (2016-2017) from different regions of Algeria and risk factors associated with the contamination.

Materials And Methods: During the survey period, 84 samples of raw milk were collected in three regions of Algeria (northeast, north center, and northwest) during four seasons.

Multimodal Change Detection in Remote Sensing Images Using an Unsupervised Pixel Pairwise Based Markov Random Field Model.

This work presents a Bayesian statistical approach to the multimodal change detection (CD) problem in remote sensing imagery. More precisely, we formulate the multimodal CD problem in the unsupervised Markovian framework. The main novelty of the proposed Markovian model lies in the use of an observation field built up from a pixel pairwise modeling and on the bitemporal heterogeneous satellite image pair.

What is the Best Revascularization Strategy for Acute Occlusive Arterial Mesenteric Ischemia: Systematic Review and Meta-analysis.

Purpose: Acute mesenteric ischemia (AMI) is a life-threatening disease that leads to bowel infarction and death. The optimal management of AMI remains controversial. The present meta-analysis aimed to estimate the prognostic impact of surgical (SG) versus endovascular or hybrid intervention (EV) as the first-line treatment for acute arterial occlusive mesenteric ischemia and to assess whether endovascular strategy was actually effective in reducing bowel resection.

Effect of the chain length on the thermal and analytical properties of laterally biforked nematogens.

Three laterally substituted liquid crystals were synthesized in order to investigate the effect of a lateral biforked chain on the thermal and analytical properties. The mesogenic molecules have the same core containing four aromatic rings connected by two ester and one diazo linkages, they differ by the length of one chain within the lateral biforked substituent. The phase transition temperatures were obtained by polarized light microscopy and differential scanning calorimetry (DSC).

Vascular percutaneous transcatheter embolisation with a new device: Amplatzer vascular plug.

Purpose: The aim of this study was to evaluate the effectiveness of the new Amplatzer vascular plug (AVP) for the occlusion of vascular abnormalities and peripheral vessels, especially those with a large diameter.

Materials And Methods: The new device was used for the occlusion of five internal iliac arteries to prevent retrograde endoleak following endograft repair, three left subclavian arteries for the treatment of type II endoleaks after positioning thoracic aorta stent-grafts, one pulmonary arteriovenous malformation, one haemodialysis fistula in a patient with forearm oedema and one large gastric varix in a patient who had undergone transjugular intrahepatic portosystemic shunt (TIPS) for haemorrhage.

Results: The five internal iliac arteries and the three left subclavian arteries were successfully occluded within 8 and 5 min, respectively.

Calcific tendinitis of the rotator cuff as a cause of drooping shoulder.

We describe a case of inferior glenohumeral subluxation or drooping shoulder secondary to acute calcific tendinitis of the rotator cuff. The various etiologies of drooping shoulder and the specific causes determining glenohumeral widening in our report are discussed. The importance in recognizing this uncommon complication of a common abnormal finding and correction by aspiration is stressed.

Ultrasound of tendons and nerves.

Tendons and nerves represent probably one of the best application of musculoskeletal US due to the high lesion detection rate and accuracy of US combined with its low cost, wide availability, and ease of use. The refinement of high-frequency broadband linear-array transducers, and sensitive color and power Doppler technology, have improved the ability of US to detect fine textural abnormalities of these structures as well as to identify a variety of pathological conditions. Characteristic echotextural patterns, closely resembling the histological ones, are typically depicted in these structures using high US frequencies.

Role of ultrasonography in the staging of gastrointestinal neoplasms.

This article reviews the capabilities and limits of ultrasonography (US) in the staging of gastrointestinal neoplasms. US is a well-established tool in the investigation of abdominal diseases. Its role is very important in the first approach to liver, gallbladder, biliary, and pancreatic diseases, but its abilities for accurate staging may be limited by various factors, which will be discussed.

Cytolysis following chemoembolization for hepatocellular carcinoma.

Background: Lipiodolized chemoembolization of hepatocellular carcinoma (HCC) can induce fever and cytolysis, defined as an increase in serum levels of liver transaminases, which is frequently assumed to result from tumour necrosis. This study aimed to assess the causes of this syndrome, reviewing preoperative data, intraoperative findings, tumour necrosis and the status of non-tumorous liver.

Methods: A retrospective study was undertaken of 29 patients treated by neoadjuvant lipiodolized chemoembolization before surgical resection of HCC.

Haemoglobin J-Biskra: a new mildly unstable alpha1 gene variant with a deletion of eight residues (alpha50-57, alpha51-58 or alpha52-59) including the distal histidine.

Single point mutation, which accounts for 92% of the 700 known variants, is the most frequent genetic defect responsible for abnormal haemoglobins. Small deletions (or insertions) involving from one to five residues are also observed, but in only approximately 5% of cases. The remaining variants produce fusion or extended haemoglobins.

[Hemoglobin G Coushatta (beta 22 (B4) glu leads to ala) in Algeria: an homozygous case].

In this paper, we report the first observation of Hb G Coushatta (beta 22 (B4) Glu leads to Ala) in North Africa. An homozygous case was discovered and studied. The structural abnormality was characterized by using S.

[Clinical and biological aspects of beta-thalassemia. Apropos of 176 cases].

The study of 176 subjects with beta-thalassemia, associated or not with a hemoglobinopathy, shows great diversity. The hemoglobin C thalassemias are less severe and form a fairly homogeneous group. Sickle cell thalassemia cases have more marked anemia and the disease takes on more varied forms, no doubt because the main mechanism of the anemia, the hyperhemolysis, is influenced by several factors which have a variable effect on the clinical picture.

[Abnormal hemoglobins in Algeria].

The existence of frequent hemoglobin abnormalities raises a Public Health problem in Algeria. The presence of genes for hemoglobin S, hemoglobin C and thalassemia in various regions of the country causes severe congenital hemolytic anemias: thalassemia, sickle-cell anemia, S thalassemia, association of HbS and HbC. These diseases are often invaliding requiring frequent admissions to hospital and have a high social cost.
