A Practical Approach for the In Vitro Safety and Efficacy Assessment of an Anti-Ageing Cosmetic Cream Enriched with Functional Compounds.

(1) Background: Cosmeceuticals are topical products applied to human skin to prevent skin ageing and maintain a healthy skin appearance. Their effectiveness is closely linked to the compounds present in a final formulation. In this article, we propose a panel of in vitro tests to support the efficacy assessment of an anti-ageing cream enriched with functional compounds.

In Vitro Hair Growth Promoting Effect of a Noncrosslinked Hyaluronic Acid in Human Dermal Papilla Cells.

Dermal papilla cells (DPCs) are a source of nutrients and growth factors, which support the proliferation and growth of keratinocytes as well as promoting the induction of new hair follicles and maintenance of hair growth. The protection from reactive oxygen species (ROS) and the promotion of angiogenesis are considered two of the basal mechanisms to preserve the growth of the hair follicle. In this study, a noncrosslinked hyaluronic acid (HA) filler (HYDRO DELUXE BIO, Matex Lab S.

The Anti-Ageing and Whitening Potential of a Cosmetic Serum Containing 3--ethyl-l-ascorbic Acid.

Skin ageing has many manifestations such as wrinkles, dryness, hyperpigmentation, and uneven skin tone. Extrinsic and intrinsic factors, especially solar ultraviolet light (UVB), contribute to skin ageing; its main features are brown spots, alterations in melanin pigmentation, and a decrease in collagen and hyaluronic acid linked to oxidative stress. Several studies showed that topical products containing ingredients with antioxidant activity can reduce oxidative damage; to provide a maximum anti-ageing effect to the skin, topical products can combine various ingredients.

In Vitro Evaluation of the Effect of a Not Cross-Linked Hyaluronic Acid Hydrogel on Human Keratinocytes for Mesotherapy.

The multicomponent preparations for mesotherapy are based on the principle that skin and hair aging can be prevented by supplying the fundamental substrates for correct cellular functioning, such as nucleotides, vitamins, amino acids, and biomolecules including hyaluronic acid (HA) that promote skin hydration and several biological activities. The study provides evidence for the application of HYDRO DELUXE BIO (Matex Lab S.p.

In Vitro Embryo Production in Buffalo Species (Bubalus bubalis).

In the last years there has been a growing attention in the world regarding buffalo (Bubalus bubalis) breeding. In tropical countries, climatic and environmental conditions make buffalo an irreplaceable milk producer. Since cattle cannot express their own productive potential in these conditions, buffaloes are best suited to satisfy animal protein demand, as they are easy to maintain, long-lived, and parasite resistant.

Red grape (Vitis vinifera L.) flavonoids down-regulate collagen type III expression after UV-A in primary human dermal blood endothelial cells.

Red grape (Vitis vinifera L.) flavonoids including flavan-3-ols (eg, catechin and epicatechin), flavonols (eg, quercetin) and anthocyanins (eg, malvidin) exert anti-inflammatory and antioxidant activities. In the skin they also have a photoprotective action, and their effects have been extensively investigated in keratinocytes, melanocytes and fibroblasts.

Global transcriptome profiles of Italian Mediterranean buffalo embryos with normal and retarded growth.

The transcriptome profiles were compared for buffalo embryos with normal growth and embryos with retarded growth on Day 25 after mating. Embryos with retarded growth on Day 25 after mating have a reduced likelihood of undergoing attachment to the uterine endometrium and establishing a pregnancy. Italian Mediterranean buffaloes were mated by AI and on Day 25 underwent trans-rectal ultrasonography to ascertain embryo development.

Osteopontin improves sperm capacitation and in vitro fertilization efficiency in buffalo (Bubalus bubalis).

The aim of this study was to evaluate the effect of osteopontin (OPN), an ubiquitous acid glycoprotein, on in vitro sperm capacitation and on in vitro embryo production (IVEP) efficiency in buffalo. In experiment 1, after swim-up separation the sperm were incubated in Tyrode albumin lactate pyruvate medium in the absence of capacitating agents (control), with the standard concentration of heparin (0.01 mM) and three different concentrations of OPN (0.

Ovum pick-up and in vitro embryo production (OPU-IVEP) in Mediterranean Italian buffalo performed in different seasons.

This study was designed to evaluate the effect of season on in vivo oocyte recovery and embryo production in Mediterranean Italian buffalo (Bubalus bubalis). For this purpose repeated transvaginal ultrasound-guided ovum pick up (OPU) was conducted twice a week throughout autumn, mid-winter (transitional period) and spring-summer. The number and size of follicles was determined before puncture.

The effect of season on oocyte quality and developmental competence in Italian Mediterranean buffaloes (Bubalus bubalis).

At Italian latitudes, buffalo (Bubalus bubalis) is a seasonally polyestrous species, showing an improved reproductive efficiency when daylight decreases (autumn). The aim of the present study was to evaluate the influence of the season on buffalo oocyte recovery rate, on oocyte quality, assessed on morphological basis, and developmental competence after in vitro fertilization. For this purpose, buffalo ovaries were collected from a local abattoir and the oocytes obtained by aspirating the follicles were evaluated, classified and, if considered of good quality, devolved to the different procedures of IVEP.
