Nutritional Therapies on the Intestinal Microbiome
Inflammatory bowel disease (IBD) is a chronic, autoimmune disorder of the gastrointestinal tract with numerous genetic and environmental risk factors. Patients with Crohn’s disease (CD) or ulcerative colitis (UC) often demonstrate marked disruptions of their gut microbiome. The intestinal microbiota is strongly influenced by diet. The association between the increasing incidence of IBD worldwide and increased consumption of a westernized diet suggests host nutrition may influence the progression or treatment of IBD via the microbiome. Several nutritional therapies have been studied for the treatment of CD and UC. While their mechanisms of action are only partially understood, existing studies do suggest that diet-driven changes in microbial composition and function underlie the diverse mechanisms of nutritional therapy. Despite existing therapies for IBD focusing heavily on immune suppression, nutrition is an important treatment option due to its superior safety profile, potentially low cost, and benefits for growth and development. These benefits are increasingly important to patients. In this entry, we will describe the clinical efficacy of the different nutritional therapies that have been described for the treatment of CD and UC.

Sperm Selection for Intracytoplasmic Sperm Injection
Intracytoplasmic sperm injection (ICSI) is the method that has definitely revolutionized the field of ART since normal fertilization and ongoing pregnancies can be achieved even with low quality sperm samples and affected spermatozoa. By injecting a single sperm cell in the oocyte, the technique bypasses several biological barriers that naturally select the gametes to achieve optimal embryonic and fetal development.

Crohn’s Disease Exclusion Diet
The Crohn’s Disease Exclusion Diet (CDED) is a new generation of nutritional therapy—in its initial stages, aimed at inducing remission, it involves a combination of partial enteral nutrition (PEN) with selected natural diet products. The primary mechanism of action is to exclude or limit exposure to dietary factors with potentially deleterious effects on the pathogenesis and course of CD.

Miscarriage and Grief
Miscarriage and grief are both an event and subsequent process of grieving that develops in response to a miscarriage. Almost all those experiencing a miscarriage experience grief. This event is often considered to be identical to the loss of a child and has been described as traumatic. But the vast majority of those who have suffered both will tell you they are nothing alike. Losing a child is in a category of its own when it comes to grief. "Devastation" is another descriptor of miscarriage. Grief differs from the emotion sadness. Sadness is an emotion along with grief, on the other hand, is a response to the loss of the bond or affection was formed and is a process rather than one single emotional response. Grief is not equivalent to depression. Grief also has physical, cognitive, behavioral, social, cultural, and philosophical dimensions. Bereavement and mourning refer to the ongoing state of loss, and grief is the reaction to that loss. Emotional responses may be bitterness, anxiety, anger, surprise, fear, and disgust and blaming others; these responses may persist for months. Self-esteem can be diminished as another response to miscarriage. Not only does miscarriage tend to be a traumatic event, women describe their treatment afterwards to be worse than the miscarriage itself. A miscarriage can often be "heart-breaking". A miscarriage can affect the women, husband, partner, siblings, grandparents, the whole family system and friends. Almost all those experiencing a miscarriage go through a grieving process. Serious emotional impact is usually experienced immediately after the miscarriage. Some may go through the same loss when an ectopic pregnancy is terminated. In some, the realization of the loss can take weeks. Providing family support to those experiencing the loss can be challenging because some find comfort in talking about the miscarriage while others may find the event painful to discuss. The father of the baby can have the same sense of loss. Expressing feelings of grief and loss can sometimes be harder for men. Some women are able to begin planning their next pregnancy after a few weeks of having the miscarriage. For others, planning another pregnancy can be difficult. Organizations exist that provide information and counselling to help those who have had a miscarriage. Some women have a higher risk of developing prolonged grief and complicated grief than others. A factor that can affect grief for men is finding help in an environment that is traditionally women-focused for maternity care and support.

The Polarized Cardiac Arrest
The concept of “polarized arrest” is attractive because maintaining the membrane potential close to the resting potential value reduces the untoward effects of Ca2+ loading. A polarised tissue is also more resistant to ischemia and inflammations reported by several in vitro and animal studies. The future of polarized arrest is an exciting one and may play an important role in treating the next generation of patients who are older, sicker with multiple comorbidities and require more complex operations with prolonged cross-clamping times.

Specialized Pro-Resolving Mediators in Neuroinflammation
Specialized pro-resolving mediators (SPMs) are lipid mediators derived from poly-unsaturated fatty acids (PUFAs) which have been demonstrated to play an important role in the inflammation environment, preventing an overreaction of the organism and promoting the resolution of inflammation.

The Role of Curcumin in Chronic Disorders
Curcumin is the primary polyphenol in turmeric’s curcuminoid class. It has a wide range of therapeutic applications, such as anti-inflammatory, antioxidant, antidiabetic, hepatoprotective, antibacterial, and anticancer effects against various cancers, but has poor solubility and low bioavailability.

Chios Mastic Gum (Pistacia lentiscus) for Human Health
Despite the remarkable development of the medical industry in the current era, herbal products with therapeutic potentials arise as attractive alternative treatments. Consequently, Chios mastiha, a natural, aromatic resin obtained from the trunk and brunches of the mastic tree, has recently gained increasing scientific interest due to its multiple beneficial actions. Chios mastiha is being exclusively produced on the southern part of Chios, a Greek island situated in the northern Aegean Sea, and its therapeutic properties have been known since Greek antiquity. There is now substantial evidence to suggest that mastiha demonstrates a plethora of favorable effects, mainly attributed to the anti-inflammatory and anti-oxidative properties of its components. The main use of mastiha nowadays, however, is for the production of natural chewing gum, although an approval by the European Medicines Agency for mild dyspeptic disorders and for inflammations of the skin has been given.

Excipients to Inhibit Efflux Transporters
Efflux transporters distributed at the apical side of human intestinal epithelial cells actively transport drugs from the enterocytes to the intestinal lumen, which could lead to extremely poor absorption of drugs by oral administration. Efflux transporters in the gastrointestinal tract mainly include P-gp, MRPs and BCRP.

Anticancer Activity of Berberine
Berberine is a plant metabolite belonging to the group of isoquinoline alkaloids with strong biological and pharmacological activity. Currently, berberine is receiving considerable interest due to its anticancer activity based on many biochemical pathways, especially its proapoptotic and anti-inflammatory activity. Therefore, the growing number of papers on berberine demands summarizing the knowledge and research trends. The efficacy of berberine in breast and colon cancers seems to be the most promising aspect. Many papers focus on novel therapeutic strategies based on new formulations or search for new active derivatives. The activity of berberine is very important as regards sensitization and support of anticancer therapy in combination with well-known but in some cases inefficient therapeutics. Currently, the compound is being assessed in many important clinical trials and is one of the most promising and intensively examined natural agents.
