Capsulorhexis is an important step in phacoemulsification surgery. A surgeon creates a continous curvilinear tear on the anterior lens capsule by controlling the tearing vector forces. A peripherally extended tear is a serious complication. This video demonstrates a novel technique of rescuing capsular radial tear out using a cystotome.

A parasite-rescue and transformation assay with THP1 cells infected in vitro with Leishmania donovani has been optimized for anti-leishmanial drug screening. The assay involves differentiation of THP1 cells, infection with promastigotes, treatment with test drugs, controlled lysis of the infected macrophages, rescue of amastigotes, transformation to promastigotes and monitoring promastigote growth and proliferation with a fluorometric assay.

We describe a method for depletion-rescue experiments that preserves cellular integrity and protein homeostasis. Adenofection enables functional analyses of proteins within biological processes that rely on finely tuned actin-based dynamics, such as mitotic cell division and myogenesis, at the single-cell level.
FAQs
A convincing result requires that the compound produce a meaningful shift in the altered phenotype relative to the untreated perturbed system. The interpretation depends on how the compound acts: it may modulate the affected pathway, compensate for its disruption, or reverse a response caused by another drug. These distinct possibilities help connect phenotypic recovery with pathway function.
Comparing treated and untreated cells or model systems establishes whether the observed phenotype changes after compound exposure. This comparison provides the basis for judging rescue rather than attributing recovery to the original perturbation alone. In cancer studies, the contrast can strengthen conclusions about whether a molecular pathway contributes to a disease-associated phenotype.
Pharmacological rescue can be interpreted differently depending on the initiating perturbation. A genetic change may alter gene function, whereas a chemical or environmental perturbation may affect cells through a different disturbance. Testing whether a compound restores the phenotype across such contexts helps researchers assess pathway involvement and interpret gene-function studies more precisely.
The workflow begins by establishing the altered cellular or model-system phenotype, then exposing matched systems to the selected drug or bioactive compound. Researchers subsequently compare treated and untreated conditions to determine whether the affected function or phenotype changes. The result is interpreted in relation to pathway modulation, compensation, or reversal of a drug-induced response.
In cancer research, a rescue result can support therapeutic-target validation when restoring the affected phenotype depends on modulating the implicated pathway. It links a pathway-level intervention to a disease-associated cellular outcome. Such evidence helps researchers interpret gene-function studies more precisely, especially when a perturbation has produced a phenotype whose molecular basis remains uncertain.
Pharmacological rescue is useful for examining tumor-cell survival and drug resistance because a compound can reveal whether changing a particular pathway alters the response produced by another treatment. The findings may identify a pathway that supports survival or resistance and can inform rational combination treatments. The approach thus connects mechanistic observations with treatment-design decisions.
