16S rRNA Next-Generation Sequencing
The 16S rRNA gene is highly conserved in all bacteria (and also archaea). Nonetheless, it contains nine hypervariable regions (V1 - V9), where sequences of these regions can be used to identify and discriminate bacterial genus, sometimes until the species level. This makes the gene a useful tool for phylogenetic studies. With the introduction of next-generation sequencing technologies, 16S rRNA next-generation sequencing (16SNGS) has allowed profiling of bacterial communities found in organisms and the environment, and lead to the discovery of many previously unculturable members of the bacteria kingdom.

177Lu-PSMA Therapy
177Lu-PSMA (prostate specific membrane antigen) therapy is used for metastatic castration-resistant prostate cancer (mCRPC). Although there are some different approaches regarding the use of 177Lu-PSMA therapy in different countries, this type of therapy is generally safe, with a low toxicity profile. From the oncological point of view, a PSA (prostate specific antigen) decline of ≥50% was seen in 10.6–69% of patients with mCRPC; whereas progression-free survival (PFS) was reported to be 3–13.7 months in different studies. Consequently, 177Lu-PSMA therapy is a promising treatment in patients with mCRPC, with good clinical efficacy, even in heavily pretreated patients with multiple lines of systemic therapy. Currently, there are ongoing clinical trials in the United States, including a phase III multicenter FDA registration trial.

18F-Fluorodeoxyglucose (FDG) in Atherosclerosis
18F-Fluorodeoxyglucose (FDG) is a glucose analogue and the most-validated radiotracer for imaging high metabolically active inflammatory cells (e.g., macrophages) and tissues (e.g., atherosclerotic plaques) in animal models and humans [10]. The results have proven to be reproducible and modifiable via interventions that are anti-inflammatory [11]. FDG-PET imaging may mirror inflammatory activity in atherosclerosis due to the consumption of large amounts of glucose by inflammatory cells compared to other plaque cells.

1q21.1 CNV in Neuropsychiatric Disorders
The 1q21.1 CNVs, rare and large chromosomal microduplications and microdeletions, are detected in many patients with NDs. Phenotypes of duplication and deletion appear at the two ends of the spectrum. Microdeletions are predominant in individuals with schizophrenia (SCZ) and microcephaly, whereas microduplications are predominant in individuals with autism spectrum disorder (ASD) and macrocephaly.

2-[18F]FDG PET/CT
PET (positron emission tomography) is a noninvasive functional imaging technique based on the detection of photons resulting from the annihilation of positrons emitted by a radioactive substance known as radiotracer or radiopharmaceutical. PET equipments usually incorporate a computed tomography scanner (PET/CT) in order to obtain hybrid functional-anatomical images. Different radiotracers are used to study different physiologic processes, such as blood flow, bone turnover or expression of certain cell receptors. The most common radiotracer used in clinical practice is 2-deoxy-2-[18F]fluoro-d-glucose (2-[18F]FDG), a glucose analogue binded to a radioactive isotope of fluor that informs about glucose metabolism in the body. As cancer cells have high energy requirements (and, therefore, high glucose consumption), this radiotracer is mostly used to evaluate oncologic processes (disease extension, response to treatment, etc.). However, some types of cancer have low 2-[18F]FDG uptake (e.g., well-differentiated or slow-growing neoplasms), and others can have a variable uptake due to the action of certain enzymes in the metabolic route of glucose (e.g., hepatocellular carcinoma).

2-Hydroxybutyric Acid for Insulin Resistance
Diabetes mellitus type 2 (T2D), commonly known as non-insulin-dependent diabetes mellitus (NIDDM) is responsible for up to 95% of diabetic cases worldwide. It is defined as a chronic condition characterized by the loss and/or dysfunction of β-cells and insulin resistance (IR) in effector tissues, which is immediately recognized by an increase in glucose levels in the bloodstream, i.e., hyperglycemia.

2014 Taiwan Food Scandal
The 2014 Taiwan food scandal refers to a series of food safety incidents in Taiwan that came to light in 2014. Adulteration of cooking oil with recycled waste oil and animal feed oil was discovered in September 2014. Despite coming to light only in 2014, mass food adulteration by Taiwanese food conglomerates, however, has been suppressed for decades, and the food safety crisis has been among the reasons for the electoral defeat of the Kuomintang in late 2014. At least 1,256 businesses were affected in the gutter oil scandal. In November 2014, it was found that dried tofu products (a.k.a. dougan 豆乾) have been adulterated with an industrial dye, methyl yellow (a.k.a. dimethyl), for some 20 years. In December 2014, it was furthermore found that even regular non-dyed tofu has been found contaminated with carcinogens, resulting in over 25,000 kg recalled.
