Pulsed vacuum drying of fruits, vegetables, and herbs: Principles, applications and future trends.

Pulsed vacuum drying (PVD) is a novel vacuum drying method that has demonstrated significant potential in improving energy efficiency and product quality in the drying of foods and agricultural products. The current work provides a comprehensive analysis of the latest advancements in PVD technology, including its historical development, fundamental principles, and mechanistic aspects. The impact of periodic pulsed pressure changes between vacuum and atmospheric pressure on heat and moisture transfer, as well as structural changes in foods at micro- and macro-scales, is thoroughly discussed.

Long noncoding RNA LINC00284 facilitates cell proliferation in papillary thyroid cancer via impairing miR-3127-5p targeted E2F7 suppression.

Accumulating evidence has suggested that long noncoding RNAs (lncRNAs) exert crucial modulation roles in the biological behaviors of multiple malignancies. Nonetheless, the specific function of lncRNA LINC00284 in papillary thyroid cancer (PTC) remains not fully understood. The objective of this research was to explore the influence of LINC00284 in PTC and elucidate its potential mechanism.

Clinicopathological and Prognostic Value of Long Noncoding RNA SNHG15 in Human Cancers: a Meta-Analysis and Bioinformatics.

Background: Recently, accumulating evidence has suggested that the long noncoding RNA small nucleolar RNA host gene 15 (lncRNA SNHG15) was elevated in various malignancies and correlated to poor clinical outcome of patients. However, the prognosis value of SNHG15 in tumors remains not well understood.

Methods: The PubMed, Web of Science, Embase, Ovid, Cochrane Library databases were used to search for eligible articles.

The far-upstream element-binding protein 2 is correlated with proliferation and doxorubicin resistance in human breast cancer cell lines.

Far-upstream element (FUSE)-binding protein 2 (FBP2) was a member of single-stranded DNA-binding protein family; it played an important role in regulating transcription and post-transcription and is involved in the regulation of C-MYC gene expression in liver tumors. However, the role of FBP2 in breast cancer and its mechanism has not been studied yet. Here, we discovered that FBP2 was up-regulated in breast cancer tissues and breast cancer cell lines.

Influence of Genetic Background on Anthocyanin and Copigment Composition and Behavior during Thermoalkaline Processing of Maize.

Visual color is a primary quality factor for foods purchase; identifying factors that influence in situ color quality of pigmented maize during processing is important. Twenty-four genetically distinct pigmented maize hybrids (red/blue, blue, red, and purple) were used to investigate the effect of pigment and copigment composition on color stability during nixtamalization and tortilla chip processing. The red/blue and blue samples generally contained higher proportions of acylated anthocyanins (mainly cyanidin-3-(6″-malonylglucoside)) than the red and purple color classes.

Trafficking protein particle complex 6A delta (TRAPPC6AΔ) is an extracellular plaque-forming protein in the brain.

Tumor suppressor WWOX is involved in the progression of cancer and neurodegeneration. Here, we examined whether protein aggregation occurs in the brain of nondemented, middle-aged humans and whether this is associated with WWOX downregulation. We isolated an N-terminal internal deletion isoform, TPC6AΔ, derived from alternative splicing of the TRAPPC6A (TPC6A) gene transcript.

Interaction of Sorghum Tannins with Wheat Proteins and Effect on in Vitro Starch and Protein Digestibility in a Baked Product Matrix.

Carbohydrates contribute the most dietary calories, which makes starchy foods a logical target for modifying calorie intake. This study investigated the interaction of sorghum bran proanthocyanidins (PA) with proteins during wheat flour tortilla processing and impact on in vitro starch digestibility. Brans from wheat, white (low in phenols), brown (high PA), and black (high monomeric flavonoids) sorghum were used.

Enhanced action of apigenin and naringenin combination on estrogen receptor activation in non-malignant colonocytes: implications on sorghum-derived phytoestrogens.

Activation of estrogen receptor-β (ERβ) is an important mechanism for colon cancer prevention. Specific sorghum varieties that contain flavones were shown to activate ER in non-malignant colonocytes at low concentrations. This study aimed to determine positive interactions among estrogenic flavonoids most relevant in sorghum.

Thermal stability of 3-deoxyanthocyanidin pigments.

3-Deoxyanthocyanidins are promising natural colourants due to their unique properties compared to anthocyanins. However, thermal stability of 3-deoxyanthocyanidins is largely unknown. Thermal stability of crude and pure 3-deoxyanthocyanidins was determined at 95 °C/2 h and 121 °C/30 min, at pH 1-7 using HCl, formic or citric acid as acidulants.

Proanthocyanidin profile of cowpea (Vigna unguiculata) reveals catechin-O-glucoside as the dominant compound.

Proanthocyanidin (PA) profile and content can have important nutritional and health implications on plant foods. Six diverse cowpea phenotypes (black, red, green, white, light-brown and golden-brown) were investigated for PA composition using normal-phase HPLC and reversed-phase UPLC-TQD-MS. Catechin and (epi)afzelechin were the major flavan-3-ol units.

Sorghum phenolics demonstrate estrogenic action and induce apoptosis in nonmalignant colonocytes.

Evidence indicates sorghum may be protective against colon cancer; however, the mechanisms are unknown. Estrogen is believed to protect against colon cancer development by inducing apoptosis in damaged nonmalignant colonocytes. Three sorghum extracts (white, red, and black) were screened for estrogenic activity using cell models expressing estrogen receptor α (ER-α; MCF-7 breast cancer cells) and β [ER-β; nonmalignant young adult mouse colonocytes (YAMC)].

Sorghum 3-deoxyanthocyanins possess strong phase II enzyme inducer activity and cancer cell growth inhibition properties.

3-Deoxyanthoxyanins (3-DXA) possess unique chemical and biochemical properties and may be useful in helping reduce incidence of gastrointestinal cancer. This study tested sorghum extracts rich in 3-DXA as well as isolated and synthetic 3-DXA for potential to induce activity of phase II enzymes in murine hepatoma cells using the NAD(P)H:quinone oxidoreductase (NQO) assay and to inhibit proliferation of the HT-29 human colon cancer cells using MTT and PicoGreen assays. Crude black sorghum extract that contained high levels of methoxylated 3-DXA was a strong inducer of NQO activity (3.
