Considering their outstanding mechanical character, it is inevitable to utilize titanium and titanium composite for biomedical engineering application [1-6]. However, the particles releasing from these bulks or composites of biomaterials after long term implanting in human body will cause cell apoptosis or cell death, inflammation, bone

Tumor node metastasis (TNM) staging system is the most useful method in predicting prognosis of colorectal cancer (CRC), the third most common cause of death worldwide, even if other biological markers are currently under evaluation to assess their role in affecting CRC outcome and planning the best tailored therapeutic approach. Several molecular factors are being demonstrated to be effective in influencing both overall survival (OS) and disease-free survival (DFS) in CRC, acting on different aspects of tumor promoting and progression.

Fluoropyrimidines compose the backbone of regimens to treat many common solid tumors, including gastrointestinal (GI), breast and head/neck. As we continue to use these agents routinely, recognition of rare but real toxicities, such as cardiotoxicity, has also improved. The treatment options for patients who have encountered fluoropyrimidine-induced cardiotoxicity are limited as many anti-angiogenic drugs also pose a cardiac risk.

Results of epidemiological studies show that obesity and type 2 diabetes mellitus have become a public health concern globally, which has substantial health, social and economic impacts. A common characteristic of human obesity and type 2 diabetes is insulin resistance, which a given amount of insulin produces less than normal physiological responses, usually demonstrated as diminished glucose lowering effect of insulin.

Background: The precise role of corticosteroids for treatment of coronavirus disease 2019 (COVID-19) is unclear due to lack of randomized trials. Objective: To review the therapeutic value of corticosteroids for treatment of hospitalized patients with COVID-19 with more emphasis on randomized trials. Methods: English literature search of electronic databases supplemented by manual search up to June 29, 2020. Search terms included corticosteroids, COVID-19, dexamethasone, methylprednisolone, hydrocortisone, mortality, safety. Randomized trials were the main focus of research, but observational studies were also reviewed.

Neurogenic lower urinary tract dysfunction (NLUTD) is highly prevalent in poststroke patients, leading to major impact on the quality of life (QoL) and healthcare resources. Pelvic floor muscle training (PFMT) has, over the past two decades, been recommended as first-line treatment for neurologically healthy patients with lower urinary tract symptoms (LUTS). 

According to the World Health Organization (WHO), the human papillomavirus (HPV) affects more than 600 million people worldwide, being the most common sexually transmitted disease (STD). There were over 250,000 deaths due to cervical cancer worldwide and most of them took place in developing countries (WHO). There are more than 80 HPV types and more than 40 infect the genital tract

Nausea and vomiting are protective defense mechanisms by which vomit competent species avoid ingestion of potentially toxic substances. More specifically, vomiting is the act of forceful expulsion of gastrointestinal contents through the mouth, whereas nausea is an unpleasant painless subjective feeling that one will imminently vomit.

Hepatitis B virus (HBV) chronically infects more than 250 million individuals worldwide and is responsible for more than 800,000 deaths per year by promoting end-stage liver diseases, among which decompensated cirrhosis and hepatocellular carcinoma (HCC) (WHO, July 2020) are prominent. Studies performed in chimpanzees or in animalversion of HBV (woodchuck HBV: WHBV) highlighted the lack of immune responses against the virus upon primary infection.

Alzheimer’s disease (AD) is an age-related neurodegenerative disorder [1] and the most common cause of human dementia, accounting for approximately 60%?80% of cases. It is estimated that more than 30 million AD patients, and the number likely to increase to over 100 million by 2050 because of the increase of the elderly population [2].

Alpha-fetoprotein (AFP) is a tumorous marker for the diagnosis of hepatocellular carcinoma (HCC), it is synthesized mainly by the embryo yolk sac, fetal liver and the gastrointestinal tract. AFP belongs to the family of protein products of albuminoid genes, which are located in tandem arrangement in chromosome 4 (region 4q11-q13).

Competent human DNA mismatch repair (MMR) corrects DNA polymerase mistakes made during cell replication to maintain complete DNA fidelity in daughter cells; faulty DNA MMR occurs in the setting of inflammation and neoplasia, creating base substitutions (e.g. point mutations) and frameshift mutations at DNA microsatellite sequences in progeny cells. Frameshift mutations at DNA microsatellite sequences are a detected biomarker termed microsatellite instability (MSI) for human disease, as this marker can prognosticate and determine therapeutic approaches for patients with cancer.

Ovarian cancer stands as the most lethal gynecologic malignancy and remains the fifth most common gynecologic cancer. Poor prognosis and low five-year survival rate are attributed to nonspecific symptoms at early phases along with a lack of effective treatment at advanced stages. It is thus paramount, that ovarian carcinoma be viewed through several lenses in order to gain a thorough comprehension of its molecular pathogenesis, epidemiology, histological subtypes, hereditary factors, diagnostic approaches, and methods of treatment.

With increasing rates of obesity, rates of type 2 diabetes and diabetic complications are expected to rise exponentially over the next few decades (American Diabetic Association). A key feature of type 2 diabetes is a resistance to insulin. Insulin signaling is key to a number of physiological processes, including glucose metabolism, cell growth, general gene expression, and apoptosis.

Acute respiratory distress syndrome (ARDS) is the major cause of mortality among hospitalized acute lung injury (ALI) patients. Lung macrophages play an important role in maintaining the tissue-fluid homeostasis following injury. We recently showed that circulating monocytes recruited into the alveolar space suppressed the stimulator of type 1 interferon genes (STING) signaling in alveolar macrophages through sphingosine-1-phosphate (S1P). 

To explore the pathological mechanism and clinical treatment of cerebellar infarction through the clinical imaging changes of cerebellar infarction.

β-Catenin is the central modulator of the canonical Wnt signaling pathway. Upon Wnt on state, β-Catenin is translocated to the nucleus and function as a transcription coactivator for several oncogenes. In Wnt off state, β-catenin is mostly localized in the cytoplasm and sequestered by the destruction complex, the negative regulator of β-catenin expression [2,3].

Adhesive capsulitis (AC), also known as ‘frozen shoulder’, is characterized by the development of dense adhesions and capsular thickening leading to a progressive and painful restriction of shoulder range of motion (ROM) and functional disability [1]. The onset is gradual, usually occurs between the ages of 40 and 60 years and is more common in females and diabetics.

The intestinal microbiota creates a bodily barrier for invading pathogen by using aggressive exclusion. Pathogens and immune cells can interact directly and dynamically with symbiotic bacteria, determining the pathophysiology and outcome of an infection. They can defend the host through a variety of processes, including attachment site occupancy, nutrition intake, metabolite competition, and the synthesis of antimicrobial compounds including bacteriocins that influence pathogen survival (a process referred to as colonization resistance).

Damage to the nervous system can have direct and indirect impact on the lower urinary tract. Broadly speaking, damage can be grouped into three categories: problems with bladder storage, stress incontinence, and problems with bladder emptying [1].
