Factors Affecting the Risk of Infection01:26

Factors Affecting the Risk of Infection

13.5K
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

Factors Affecting Dissolution: Polymorphism, Amorphism and Pseudopolymorphism01:21

Factors Affecting Dissolution: Polymorphism, Amorphism and Pseudopolymorphism

714
Polymorphism refers to the existence of a drug substance in multiple crystalline forms, known as polymorphs. Recently, this term has been expanded to include solvates (forms containing a solvent), amorphous forms (non-crystalline forms), and desolvated solvates (forms from which the solvent has been removed).
Some polymorphic crystals possess lower aqueous solubility than their amorphous counterparts, leading to incomplete absorption. For instance, the oral suspension of Chloramphenicol, which...

Line Loss01:10

Line Loss

541
The different configurations of source-load connections include wye (star) and delta connections. The relationship between line and phase voltages and currents varies depending on the configuration. When the source is supplying power, it is transmitted through the wires to the load, and during this transmission, some power is absorbed by the wires, leading to line loss.
Line loss impacts power delivery efficiency in a balanced three-phase circuit. The symmetry in such a circuit simplifies the...

Relative Risk01:12

Relative Risk

2.1K
Relative risk (RR) is a statistical measure commonly used in epidemiology to compare the likelihood of a particular event occurring between two groups. This metric is important for evaluating the relationship between exposure to a specific risk factor and the probability of a particular outcome. It plays a crucial role in medical research, public health studies, and risk assessment. Relative risk quantifies how much more (or less) likely an event is to occur in an exposed group compared to an...

Reducing Line Loss01:18

Reducing Line Loss

385
In a three-phase circuit, line loss is an indicator of energy dissipated as heat due to the resistance of transmission lines. To address this, incorporating transformers into the system—a step-up transformer at the source and a step-down transformer at the load—is a strategic solution. Two three-phase transformers are introduced to improve this.
With a step-up transformer at the source, the voltage is increased, thereby reducing the current in the transmission lines since power loss in...

Single Nucleotide Polymorphisms-SNPs01:05

Single Nucleotide Polymorphisms-SNPs

18.3K
A single nucleotide polymorphism or SNP is a single nucleotide variation at a specific genomic position in a large population. It is the most prevalent type of sequence variation found in the human genome. Point mutations that occur in more than 1% of the population qualify as SNPs. These are present once every 1000 nucleotides on an average in the human genome. Replacement of a purine with another purine (A/G) or a pyrimidine with another pyrimidine (C/T) is known as a transition. In contrast,...

    Summary

    The MMP-13 g.-77 A > G (rs2252070) gene polymorphism, specifically the A allele, is linked to an increased risk of early dental implant loss. This genetic factor may play a role in implant failure.

    Area of Science:

    • Genetics and Oral Health
    • Dental Implantology
    • Molecular Biology

    Background:

    • Early dental implant loss is a significant clinical concern.
    • Genetic predispositions may influence implant survival rates.
    • Matrix metalloproteinase-13 (MMP-13) plays a role in tissue remodeling and inflammation.

    Purpose of the Study:

    • To investigate the association between the MMP-13 g.-77 A > G (rs2252070) gene polymorphism and early dental implant loss.
    • To determine if specific alleles or genotypes of MMP-13 are risk factors for implant failure.

    Main Methods:

    • A case-control study involving 200 periodontally healthy volunteers.
    • Participants were divided into a control group (healthy implants) and a test group (early implant loss).
    • Genomic DNA from saliva was analyzed using PCR-RFLP for MMP-13 genotyping.

    Main Results:

    • A significant difference in MMP-13 g.-77 A > G polymorphism was observed between groups (P = .0161).
    • The A allele was associated with increased susceptibility to early implant loss (OR 95% = 0.57).
    • The A allele appears to be a genetic risk factor for early implant failure.

    Conclusions:

    • The MMP-13 g.-77 A > G (rs2252070) polymorphism may be a contributing factor to early dental implant loss.
    • Genetic screening for this polymorphism could potentially identify individuals at higher risk.
    • Further research is warranted to elucidate the precise mechanisms involved.
